 ## Feature Implementation Guide
-### v1.5.0 Enhanced Features & Open Source Compatibility (Latest)
+### v1.9.1 ASCII Art & Code Block Preservation (Latest)
 #### 🎨 Preserved ASCII Art in Exports
 **ASCII Art, Charts, Tables & Flowcharts Now Export Exactly as Previewed** (`src/wordTemplateExporter.js`, `src/main.js`)
 **Problem Solved:**
 - Previously, ASCII art, flowcharts, and code blocks were being corrupted during export to Word and PDF
 - Line breaks, spacing, and monospace alignment were lost
 - Box-drawing characters and diagrams became unreadable
 **Solution Implemented:**
 1. **Enhanced Word Template Exporter** (`src/wordTemplateExporter.js:259-289`)
   - Code blocks now render each line as a separate paragraph with exact spacing
   - `white-space: pre` and `word-wrap: normal` prevent text wrapping
   - Monospace font (Consolas) with consistent 18pt size
   - Light gray background (#F5F5F5) for visual distinction
   - `<w:keepLines/>` and `<w:wordWrap w:val="0"/>` preserve exact formatting
 2. **Improved ASCII Art Detection** (`src/wordTemplateExporter.js:410-456`)
   - Extended Unicode box-drawing character support (╭╮╯╰ rounded corners, heavy box characters)
   - Additional arrow characters (↔↕⇒⇐⇓⇑)
   - More ASCII patterns detected (+---+---+, <---->, etc.)
   - Better markdown table vs ASCII art differentiation
 3. **Enhanced PDF Export** (`src/main.js:1266-1268`, `src/main.js:1345-1347`, `src/main.js:2410-2412`)
   - Added `-V monofont="Consolas"` for monospace code blocks
   - Added `--highlight-style=tango` for syntax highlighting
   - Applied to main export, fallback export, and CLI conversion
 4. **Electron PDF Fallback** (`src/main.js:1613-1637`)
   - Enhanced CSS for `<pre>` and `<code>` elements
   - `white-space: pre` prevents wrapping
   - `font-family: Consolas, Monaco, 'Courier New', monospace`
   - Print media query preserves formatting when printing
 5. **HTML Export** (`src/main.js:1525-1548`)
   - Same CSS improvements as Electron PDF
   - Code blocks maintain exact preview appearance
 **Key CSS Properties for ASCII Preservation:**
 ```css
 pre {
    white-space: pre;
    word-wrap: normal;
    font-family: Consolas, Monaco, 'Courier New', monospace;
    font-size: 12px;
    line-height: 1.4;
 }
 pre code {
    white-space: pre;
    word-wrap: normal;
    display: block;
 }
 ```
 **Word XML Properties for ASCII Preservation:**
 ```xml
 <w:pPr>
    <w:spacing w:line="240" w:lineRule="exact"/>
    <w:keepLines/>
    <w:wordWrap w:val="0"/>
 </w:pPr>
 <w:rPr>
    <w:rFonts w:ascii="Consolas" w:hAnsi="Consolas" w:cs="Consolas"/>
    <w:noProof/>
 </w:rPr>
 ```

 ### v1.9.0 Custom Headers & Footers
 #### 📄 Comprehensive Header & Footer System
 **Custom Headers & Footers for Standard Exports** (`src/main.js:701-853`, `src/index.html:929-1042`, `src/renderer.js:2560-2747`, `src/styles.css:3162-3432`)
 - **New Menu Option**: File → "Header & Footer Settings..." to configure headers/footers
 - **Three-Column Layout**: Left, Center, and Right positioning for both headers and footers
 - **Dynamic Field Support**: $PAGE$, $TOTAL$, $DATE$, $TIME$, $TITLE$, $AUTHOR$, $FILENAME$
 - **Logo/Image Embedding**: Upload logos to display in headers and footers
 - **Enable/Disable Toggle**: Quick on/off switch for all headers/footers
 - **Persistent Settings**: Configurations saved across sessions
 **Format Support:**
 - **PDF Export** (Standard): LaTeX-based headers/footers using fancyhdr package with automatic page numbering
 - **DOCX Export** (Standard): Word XML manipulation with field support for PAGE and NUMPAGES
 - **ODT Export**: OpenDocument format support (similar to DOCX implementation)
 - **PowerPoint (PPTX)**: Footer text with dynamic fields on slides
 - **Batch Converter**: Full header/footer support for all batch conversions
 **Dynamic Fields Processing:**
 - `$PAGE$` → Current page number (LaTeX: \thepage, Word: PAGE field)
 - `$TOTAL$` → Total pages (LaTeX: \pageref{LastPage}, Word: NUMPAGES field)
 - `$DATE$` → Current date (processed at export time)
 - `$TIME$` → Current time (processed at export time)
 - `$TITLE$` → Document title (from metadata or filename)
 - `$AUTHOR$` → Document author (from metadata)
 - `$FILENAME$` → File name without extension
 **Technical Implementation:**
 ```javascript
 // processDynamicFields function in main.js
 function processDynamicFields(text, metadata = {}) {
  const now = new Date();
  result = text.replace(/\$DATE\$/g, now.toLocaleDateString());
  result = result.replace(/\$TIME\$/g, now.toLocaleTimeString());
  result = result.replace(/\$TITLE\$/g, metadata.title || 'Untitled');
  // ... other replacements
  return result;
 }
 // LaTeX header generation for PDF exports
 const latexHeader = `
 \\usepackage{fancyhdr}
 \\pagestyle{fancy}
 \\fancyhf{}
 \\lhead{${headerLeft}}
 \\chead{${headerCenter}}
 \\rhead{${headerRight}}
 \\lfoot{${footerLeft}}
 \\cfoot{${footerCenter}} // with \\thepage for page numbers
 \\rfoot{${footerRight}}
 `;
 // Word XML generation for DOCX exports
 const footerXml = `<?xml version="1.0"?>
 <w:ftr xmlns:w="http://schemas.openxmlformats.org/wordprocessingml/2006/main">
  <w:p><w:r><w:t>${footerLeft}</w:t></w:r></w:p>
  <w:p>
    <w:fldSimple w:instr="PAGE"/> // Page number field
    <w:r><w:t> of </w:t></w:r>
    <w:fldSimple w:instr="NUMPAGES"/> // Total pages field
  </w:p>
  <w:p><w:r><w:t>${footerRight}</w:t></w:r></w:p>
 </w:ftr>`;
 ```
 **Dialog Features:**
 - **Field Insertion Buttons**: Quick-insert dynamic fields via popup dialog
 - **Logo Upload**: Browse and select images for headers/footers
 - **Logo Preview**: Show selected logo filename
 - **Clear Buttons**: Remove uploaded logos
 - **Enable Toggle**: Disable headers/footers without losing settings
 - **Responsive Layout**: Grid-based three-column design
 - **Dark Theme Support**: Complete styling for all 22 themes
 **Integration Points:**
 - `buildPandocCommand()` - Adds LaTeX headers for PDF exports
 - `exportWithPandoc()` - Post-processes DOCX with header/footer XML
 - `performBatchConversion()` - Batch support for all formats
 - `addHeaderFooterToDocx()` - DOCX XML manipulation using PizZip
 **Dependencies:**
 - **PizZip** (v3.2.0) - ZIP file manipulation for DOCX/ODT
 - **fancyhdr** (LaTeX package) - Advanced headers/footers for PDF
 - **lastpage** (LaTeX package) - Total page count support
 **Key Improvements in v1.9.0:**
 1. ✅ Professional headers/footers for all standard export formats
 2. ✅ Dynamic field support with automatic value replacement
 3. ✅ Logo/image embedding in document headers/footers
 4. ✅ Batch converter integration with full header/footer support
 5. ✅ Persistent settings across application sessions
 6. ✅ User-friendly dialog with field insertion helper
 7. ✅ Complete dark theme support
 **Note**: Enhanced exports (DOCX Enhanced, PDF Enhanced) use Word templates which already have their own headers/footers defined in the template itself, so this feature specifically targets standard (non-templated) exports.

 ### v1.7.9 Enhanced Word Export with Template Support
 #### 📝 Template-Based Word Document Generation
 **Added Enhanced DOCX Export** (`src/wordTemplateExporter.js`, `src/main.js:540-596`, `src/main.js:242`)
 - **New Export Option**: "DOCX (Enhanced)" in File → Export menu with keyboard shortcut `Ctrl+Shift+W`
 - **Template Support**: Use custom Word templates to preserve branding, styles, and formatting
 - **Template Selection**: File → "Select Word Template..." menu option to choose custom templates
 - **Persistent Template**: Selected template is saved and reused across sessions
 - **Word XML Manipulation**: Direct manipulation of Word document XML using PizZip
 - **Template Page Preservation**: Preserves first 2 pages (cover + TOC) when using templates
 - **Smart Content Insertion**: Inserts markdown content after 2nd section break
 **Full Markdown Support:**
 - Headings (H1-H6) with markdown numbering stripped (e.g., "1.1 Title" → "Title")
 - Text formatting (bold, italic, bold+italic, strikethrough)
 - Inline code with Consolas font and gray background
 - Code blocks with monospace font and light gray background
 - Ordered and unordered lists (uses template numbering, strips markdown numbering)
 - Blockquotes with indentation
 - **Tables with orange header styling**:
  - Orange header row (#F58220) with white bold text
  - White data rows (no alternating colors)
  - Orange borders (#F58220) on all cells
  - Proper column alignment and spacing
 - Horizontal rules
 - Links
 - **ASCII Art and Flowcharts**:
  - Detects box-drawing characters (┌, ─, │, └, etc.)
  - Detects flowchart patterns with square brackets
  - Preserves monospace alignment with Consolas font
  - Each line rendered separately to prevent wrapping
  - No-wrap paragraph properties for exact spacing
  - **Red-colored arrows** (↓, →, ←, ↑) for enhanced visibility
  - Gray background (#F5F5F5) for distinction from regular text
 **ASCII Art Detection Patterns:**
 - Unicode box-drawing characters: ┌┐└┘├┤┬┴┼─│═║╔╗╚╝╠╣╦╩╬
 - Arrow characters: ↓→←↑▼►◄▲
 - ASCII box patterns: +-----+, |-----|, [Text in brackets]
 - Flowchart steps: START, [Step Description], END
 **ASCII Art Rendering Features:**
 ```javascript
 // Each line gets its own paragraph with no-wrap
 xml += `<w:p>
    <w:pPr>
        <w:wordWrap w:val="0"/>          // Disable wrapping
        <w:keepLines/>                    // Keep lines together
        <w:line="240" w:lineRule="exact"/>  // Exact line height
    </w:pPr>
    // Arrows colored red (#FF0000)
    // Text in Consolas 16pt with gray background
 </w:p>`;
 ```
 **Template Selection Workflow:**
 1. User clicks File → "Select Word Template..."
 2. Dialog opens to browse for .docx files
 3. Selected template path stored in global variable and persisted
 4. Template automatically loaded on app startup
 5. Enhanced export uses selected template (or defaults to `word_template.docx`)
 **Technical Implementation:**
 ```javascript
 // Template selection function
 async function selectWordTemplate() {
    const result = await dialog.showOpenDialog(mainWindow, {
        title: 'Select Word Template',
        filters: [{ name: 'Word Document', extensions: ['docx'] }],
        properties: ['openFile']
    });
    if (!result.canceled && result.filePaths.length > 0) {
        wordTemplatePath = result.filePaths[0];
        store.set('wordTemplatePath', wordTemplatePath);
    }
 }
 // Word Template Exporter with template support
 class WordTemplateExporter {
    constructor(templatePath) {
        this.templatePath = templatePath || path.join(__dirname, '../word_template.docx');
    }
    async convert(markdownContent, outputPath) {
        // Load template as ZIP
        const templateBuffer = fs.readFileSync(this.templatePath);
        const zip = new PizZip(templateBuffer);
        // Extract and modify document.xml
        const documentXml = zip.file('word/document.xml').asText();
        const newContentXml = this.markdownToWordXml(markdownContent);
        const modifiedXml = this.insertContentAfterPage2(documentXml, newContentXml);
        // Save modified document
        zip.file('word/document.xml', modifiedXml);
        const newDocBuffer = zip.generate({ type: 'nodebuffer' });
        fs.writeFileSync(outputPath, newDocBuffer);
    }
 }
 ```
 **Menu Integration:**
 - Export: File → Export → "DOCX (Enhanced)" (`Ctrl+Shift+W`)
 - Template Selection: File → "Select Word Template..."
 - Template path saved to: `userData/settings.json`
 **Dependencies Added:**
 ```json
 {
  "docx": "^9.5.1",
  "pizzip": "^3.2.0",
  "docx4js": "^3.3.0"
 }
 ```
 **Key Improvements in v1.7.9:**
 1. ✅ Template-based export preserving corporate branding
 2. ✅ Persistent template selection across sessions
 3. ✅ Tables with professional orange header styling and white data rows
 4. ✅ ASCII art and flowcharts with perfect alignment and no wrapping
 5. ✅ Red-colored arrows in flowcharts for enhanced readability
 6. ✅ Markdown numbering stripped from headings and lists
 7. ✅ Template's automatic numbering system used instead
 ### v1.7.8 Critical Bug Fixes
 #### 🐛 File Association Fix for Packaged Apps
 **Fixed Command-Line Argument Parsing** (`src/main.js:1598-1627`, `src/main.js:70-90`)
 - **Root Cause**: `process.argv.slice(2)` works in development but fails in packaged apps
 - **Solution**: Detect if app is packaged using `app.isPackaged` and use correct slice index
  - Development: `process.argv.slice(2)` - ['electron', 'app.js', 'file.md']
  - Packaged: `process.argv.slice(1)` - ['PanConverter.exe', 'file.md']
 - **Path Resolution**: Added proper path resolution for both absolute and relative paths
 - **Comprehensive Logging**: Added detailed console logs to debug file loading issues
 - **Second Instance Handler**: Also fixed second-instance handler to use same logic
 **Technical Implementation:**
 ```javascript
 // Detect packaged vs development mode
 const startIndex = app.isPackaged ? 1 : 2;
 const fileArgs = process.argv.slice(startIndex);
 // Resolve paths properly
 for (const arg of fileArgs) {
  if ((arg.endsWith('.md') || arg.endsWith('.markdown'))) {
    const resolvedPath = path.isAbsolute(arg) ? arg : path.resolve(process.cwd(), arg);
    if (fs.existsSync(resolvedPath)) {
      app.pendingFile = resolvedPath;
      break;
    }
  }
 }
 ```
 **Fixed Issues:**
 - ✅ Files now open correctly on first double-click in packaged app
 - ✅ Command-line arguments properly parsed in both dev and production
 - ✅ Relative and absolute paths handled correctly
 - ✅ Comprehensive logging for debugging file association issues
 #### 🖨️ Print Preview Fix
 **Fixed Print Output to Show Preview Content** (`src/renderer.js:1178-1204`, `src/styles.css:2828-3014`)
 - **Root Cause**: Manual DOM manipulation conflicted with CSS `@media print` rules
 - **Solution**: Simplified handler to rely on CSS `@media print` for hiding UI elements
 - **CSS Enhancements**:
  - Added selectors for dynamic preview panes `[id^="preview-pane-"]` and `[id^="editor-pane-"]`
  - Added `.tab-content` to ensure full-width rendering
  - Added body class-based styling for no-styles mode
 - **Removed Manual Hiding**: Eliminated manual `display: none` manipulation in favor of CSS
 **Technical Implementation:**
 ```javascript
 // Simplified print handler - let CSS do the work
 function handlePrintPreview(withStyles) {
  const activeTabId = tabManager ? tabManager.activeTabId : 1;
  const previewContent = document.getElementById(`preview-${activeTabId}`);
  if (!previewContent || !previewContent.innerHTML.trim()) {
    alert('Nothing to print...');
    return;
  }
  // Add body classes for CSS styling
  if (!withStyles) {
    document.body.classList.add('printing-no-styles');
  }
  document.body.classList.add('printing');
  setTimeout(() => {
    ipcRenderer.send('do-print', { withStyles });
    setTimeout(() => {
      document.body.classList.remove('printing', 'printing-no-styles');
    }, 1000);
  }, 100);
 }
 ```
 **CSS Updates:**
 ```css
@media print {
  /* Hide all UI elements */
  #toolbar, #tab-bar, .editor-pane, [id^="editor-pane-"] {
    display: none !important;
  }
  /* Show preview in full width */
  [id^="preview-"], [id^="preview-pane-"], .tab-content {
    display: block !important;
    width: 100% !important;
    padding: 20px !important;
  }
 }
 ```
 **Fixed Issues:**
 - ✅ Print now correctly renders preview content, not toolbar
 - ✅ Both print modes work (with styles and without styles)
 - ✅ Clean, professional print output with proper formatting
 - ✅ Proper page breaks, typography, and layout optimization
 #### 🔧 Development Cleanup
 **Removed Debugging Code** (`src/main.js:120-123`)
 - Removed auto-opening of DevTools
 - Clean production-ready build
 - Debugging logs remain for troubleshooting but DevTools disabled by default
 ### v1.7.7 Print & Enhanced PDF Support
 #### 🖨️ Native Print Functionality
 **Added Print Submenu to File Menu** (`src/main.js:202-215`, `src/renderer.js:1152-1188`, `src/styles.css:2828-2994`)
 - **Print Menu**: Submenu in File menu with two print options
  - **Print Preview** (`Ctrl+P`) - Prints preview in black text, no background colors (ink-saving)
  - **Print Preview (With Styles)** - Prints with full theme colors and styling
 - **Preview-Only Printing**: Only renders the markdown preview, hides all editor UI
 - **Native Print Dialog**: Uses Electron's webContents.print() for native OS print dialogs
 - **Professional Output**: Automatically hides editor, toolbar, tabs, and status bar during print
 - **Print Optimization**: Smart page breaks, proper formatting for headings, code blocks, tables
 - **Cross-Platform**: Works on Windows, macOS, and Linux with native printer support
 **Print Options:**
 1. **Print Preview** (Ctrl+P)
   - Black text on white background for professional printing
   - No background colors to save ink
   - Perfect for documents and reports
   - Minimal ink consumption
 2. **Print Preview (With Styles)**
   - Full theme colors and styling
   - Preserves markdown formatting with visual hierarchy
   - Better for design-focused documents
   - Shows code blocks with colored syntax highlighting
 **Technical Implementation:**
 ```javascript
 // Main process - two print handlers
 ipcMain.on('print-preview', (event) => {
  mainWindow.webContents.send('prepare-print-preview', false);
  setTimeout(() => {
    mainWindow.webContents.print({
      silent: false,
      printBackground: false,
      color: true,
      margin: { marginType: 'default' }
    });
  }, 100);
 });
 ipcMain.on('print-preview-styled', (event) => {
  mainWindow.webContents.send('prepare-print-preview', true);
  setTimeout(() => {
    mainWindow.webContents.print({
      silent: false,
      printBackground: true,
      color: true,
      margin: { marginType: 'default' }
    });
  }, 100);
 });
 // Renderer process - prepares preview for printing
 ipcRenderer.on('prepare-print-preview', (event, withStyles) => {
  // Hide editor and UI elements
  document.getElementById('editor-container').style.display = 'none';
  document.getElementById('toolbar').style.display = 'none';
  document.getElementById('tab-bar').style.display = 'none';
  document.getElementById('status-bar').style.display = 'none';
  // Add print mode classes
  const preview = document.getElementById('preview');
  preview.classList.add('print-mode');
  if (!withStyles) {
    preview.classList.add('print-no-styles');
  }
  // Restore UI after print
  setTimeout(() => {
    document.getElementById('editor-container').style.display = '';
    document.getElementById('toolbar').style.display = '';
    document.getElementById('tab-bar').style.display = '';
    document.getElementById('status-bar').style.display = '';
    preview.classList.remove('print-mode', 'print-no-styles');
  }, 500);
 });
 ```

 #### 📦 Enhanced PDF Export Dependencies
 **Added Native PDF Generation Libraries** (package.json)
 - **PDFKit** (v0.14.0) - Native PDF generation without Pandoc dependency
 - **html2pdf.js** (v0.10.1) - HTML to PDF conversion for rich formatted output
 - **Benefits**: PDF exports now work even without system Pandoc installation
 - **Future Enhancement**: Enables PDF generation with embedded fonts and graphics
 - **Offline Support**: Complete PDF generation offline without external services
 **Updated Dependencies:**
 ```json
 {
  "pdfkit": "^0.14.0",
  "html2pdf.js": "^0.10.1"
 }
 ```
 **Features Enabled:**
 - PDF export works independently of Pandoc installation
 - Higher quality PDF output with better formatting control
 - Support for custom fonts, images, and complex layouts
 - Faster PDF generation times
 - Reduced system dependencies for better portability
 #### 🔧 Keyboard Shortcut Updates
 **Remapped Shortcuts** (`src/main.js`)
 - **Print**: `Ctrl+P` (new in v1.7.7) - Opens native print dialog
 - **Toggle Preview**: Changed from `Ctrl+P` to `Ctrl+Shift+P` to avoid conflicts
 - **Backward Compatibility**: No breaking changes to existing workflows
 ### v1.7.6 UI Improvement
 #### 🎨 Table Header Styling Cleanup
 **Removed Custom Background Colors** (`src/styles.css:327-329`, `src/styles.css:451-453`)
 - Removed gray background color (#f6f8fa) from table headers in default theme
 - Removed dark theme table header background styling block entirely
 - Table headers now blend naturally with preview background for cleaner appearance
 - Headers maintain font-weight: 600 for visual distinction
 - All other table styling preserved (borders, alternating row colors)
 **User Feedback Implementation:**
 - Based on user feedback: "remove the theming of table headers, it looks bad"
 - Result: Professional, clean table presentation matching overall preview styling
 - Consistent with normal preview theming across all themes
 ### v1.7.5 Critical File Association Fix
 #### 🐛 Single-Instance Lock for Windows File Association
 **Fixed Installed App Double-Click Behavior** (`src/main.js:52-85`)
 - **Root Cause**: Windows launches second instance when double-clicking files with app already running
 - **Solution**: Implemented `app.requestSingleInstanceLock()` pattern
 - **Second Instance Handler**: Captures file path from new instance attempts and opens in existing instance
 - **Focus Management**: Automatically focuses and restores existing window
 - **Renderer Readiness**: Proper handling of file queue with `rendererReady` state
 **Technical Implementation:**
 ```javascript
 const gotTheLock = app.requestSingleInstanceLock();
 if (!gotTheLock) {
  app.quit();
 } else {
  app.on('second-instance', (event, commandLine, workingDirectory) => {
    // Focus existing window
    if (mainWindow) {
      if (mainWindow.isMinimized()) mainWindow.restore();
      mainWindow.focus();
    }
    // Extract and open file from second instance
    const fileArgs = commandLine.slice(2);
    for (const arg of fileArgs) {
      if ((arg.endsWith('.md') || arg.endsWith('.markdown')) && fs.existsSync(arg)) {
        if (rendererReady) {
          openFileFromPath(arg);
        } else {
          app.pendingFile = arg;
        }
        break;
      }
    }
  });
 }
 ```
 **Fixed Issues:**
 - ✅ Double-click `.md` files in Windows Explorer now opens correctly
 - ✅ Right-click "Open with PanConverter" now works in installed app
 - ✅ File association behavior now consistent between development and production
 - ✅ Single instance maintained across all file opening methods
 **Why Previous Attempts Failed:**
 - v1.7.3-1.7.4: Only added `rendererReady` checks but missed second-instance handling
 - Development testing passed but production failed (different execution paths)
 - Second instance would start, receive file, then exit without passing to first instance
