#### 📄 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.

## Pending Tasks & Future Enhancements
### v1.9.0 - Header & Footer Customization (PLANNED)
No pending tasks at this time. All planned v1.9.0 features have been completed.
#### 📋 Overview
Comprehensive header and footer customization system for all export formats (PDF, Word, Excel, ODT, PowerPoint) with support for custom text, logos, page numbers, and dynamic fields.
#### ✨ Planned Features
**Header & Footer Configuration Dialog**
- **Three-column layout**: Left, Center, Right positioning for both headers and footers
- **Custom text fields**: User-defined text in each position
- **Logo/image support**: Upload and embed logos in headers/footers
- **Dynamic fields**:
- `$PAGE$` - Current page number
- `$TOTAL$` - Total page count
- `$DATE$` - Current date
- `$TIME$` - Current time
- `$TITLE$` - Document title
- `$AUTHOR$` - Document author
- `$FILENAME$` - File name
- **Enable/disable toggle**: Quick on/off for headers and footers
- **Persistent settings**: Save preferences across sessions
**Implementation Requirements**
1. **UI Components** (`src/index.html`)
- New dialog with header/footer configuration form
- Logo upload buttons with preview
- Position selectors (left/center/right)
- Dynamic field insertion buttons
- Enable/disable checkboxes
2. **State Management** (`src/main.js`)
- `headerFooterSettings` object structure:
```javascript
{
enabled: boolean,
header: {
left: string,
center: string,
right: string,
logo: string | null
},
footer: {
left: string,
center: string,
right: string,
logo: string | null
}
}
```
- Settings persistence via `store.set('headerFooterSettings')`
- IPC handlers for dialog communication
3. **Pandoc Integration**
- Use Pandoc's `--include-in-header` and `--include-after-body` options
- Generate LaTeX header/footer code for PDF exports
- Use `--variable` for header-left, header-center, header-right, etc.
- Image embedding via `\includegraphics` in LaTeX
4. **Word Template Integration** (`src/wordTemplateExporter.js`)
- Modify Word document headers/footers via XML manipulation
- Insert custom text using `<w:hdr>` and `<w:ftr>` elements
- Embed images in headers/footers using Word relationships
- Page numbering fields: `<w:fldChar w:fldCharType="begin"/>PAGE<w:fldChar w:fldCharType="end"/>`
5. **Export Format Support**
- **PDF**: Via Pandoc LaTeX template with fancyhdr package
- **Word (DOCX)**: Direct XML manipulation of header/footer sections
- **Excel/Spreadsheet**: Not applicable (spreadsheets don't have headers/footers in same way)
- **ODT**: Via Pandoc with ODF header/footer styles
- **PowerPoint**: Slide numbers and footer text via Pandoc
**Technical Challenges**
- **Image format conversion**: Convert various image formats to those supported by each export format
- **LaTeX syntax**: Proper escaping and formatting for LaTeX headers
- **Word XML complexity**: Managing relationships and image embedding in DOCX
- **Page numbering**: Different syntax for each export format
**Menu Integration**

**File Structure**
```
