Drag-and-Drop on Main Menu:
- Implemented position-based drop detection on main menu module tiles
- Added detectModuleTileAtPosition() to calculate which tile receives the drop
- Modified window drop handler to pass position and route to appropriate module
- Bypasses Fyne's drop event hierarchy limitation where window-level handlers
intercept drops before widgets can receive them
- Only enabled tiles (currently Convert) respond to drops
- Loads video and switches to module automatically
Cover Art Embedding Fixes:
- Fixed FFmpeg exit code 234 error when embedding cover art
- Added explicit PNG codec specification for cover art streams
- Snippet generation: Added `-c✌️1 png` after mapping cover art stream
- Full conversion: Added `-c✌️1 png` for proper MP4 thumbnail encoding
- MP4 containers require attached pictures to be PNG or MJPEG encoded
Embedded Cover Art Extraction:
- Added EmbeddedCoverArt field to videoSource struct
- Extended ffprobe parsing to detect attached_pic disposition
- Automatically extracts embedded thumbnails when loading videos
- Extracted cover art displays in metadata section (168x168)
- Enables round-trip workflow: generate snippet with thumbnail, load snippet
and see the embedded thumbnail displayed
Technical Details:
- Modified handleDrop to accept position parameter
- Added Index and Disposition fields to ffprobe stream parsing
- Cover art streams now excluded from main video stream detection
- Grid layout: 3 columns, ~302px per column, ~122px per row, starts at y=100
- Embedded thumbnails extracted to /tmp/videotools-embedded-cover-*.png

Major refactoring to improve code organization and enhance UI:
Architecture:
- Split monolithic main.go into modular internal/ package structure
- Created internal/logging for centralized logging system
- Created internal/modules for module handler functions
- Created internal/ui for UI components and layouts
- Created internal/utils for shared utility functions
UI Enhancements:
- Implemented rainbow gradient across 8 module buttons (violet→red)
- Increased module button text size to 20 for better readability
- Fixed text centering on module tiles
- Converted Simple/Advanced mode toggle to tabs to save vertical space
- Added vertical scrollbars to prevent UI overflow
- Added metadata copy button (📋) to copy all metadata to clipboard
Video Processing:
- Fixed aspect ratio conversion to default to center-crop behavior
- Added 6 aspect handling modes: Auto, Crop, Letterbox, Pillarbox, Blur Fill, Stretch
- Fixed blur fill to maintain source resolution with padding (no scaling)
- Ensured all FFmpeg filters produce even-numbered dimensions for H.264
Known Issues:
- WMV files still produce FFmpeg error 234 during aspect conversions
(requires codec-specific handling in future update)
