-### v1.9.1 ASCII Art & Code Block Preservation
-
-#### 🎨 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']

-### 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);
-});
-```
-
-**CSS Print Styles** (`src/styles.css:2828-2994`)
-- Comprehensive @media print stylesheet
-- Hides all UI elements in print view
-- Optimizes preview for paper output
-- Smart page breaks for headings and tables
-- Proper formatting for code blocks, lists, tables
-- Image optimization and link handling
-- Professional typography with 12pt font size
-
-#### 📦 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
