Advanced Mode Encoder Settings:
- Added full video encoding controls: codec (H.264/H.265/VP9/AV1), encoder preset,
manual CRF, bitrate modes (CRF/CBR/VBR), target resolution, frame rate,
pixel format, hardware acceleration (nvenc/vaapi/qsv/videotoolbox), two-pass
- Added audio encoding controls: codec (AAC/Opus/MP3/FLAC), bitrate, channels
- Created organized UI sections in Advanced tab with 13 new control widgets
- Simple mode remains minimal with just Format, Output Name, and Quality preset
Snippet Generation Improvements:
- Optimized snippet generation to use stream copy for fast 2-second processing
- Added WMV detection to force re-encoding (WMV codecs can't stream-copy to MP4)
- Fixed FFmpeg argument order: moved `-t 20` after codec/mapping options
- Added progress dialog for snippets requiring re-encoding (WMV files)
- Snippets now skip deinterlacing for speed (full conversions still apply filters)
Window Layout Fixes:
- Fixed window jumping to second screen when loading videos
- Increased window size from 920x540 to 1120x640 to accommodate content
- Removed hardcoded background minimum size that conflicted with window size
- Wrapped main content in scroll container to prevent content from forcing resize
- Changed left column from VBox to VSplit (65/35 split) for proper vertical expansion
- Reduced panel minimum sizes from 520px to 400px to reduce layout pressure
- UI now fills workspace properly whether video is loaded or not
- Window allows manual resizing while preventing auto-resize from content changes
Technical Changes:
- Extended convertConfig struct with 14 new encoding fields
- Added determineVideoCodec() and determineAudioCodec() helper functions
- Updated buildConversionCommand() to use new encoder settings
- Updated generateSnippet() with WMV handling and optimized stream copy logic
- Modified buildConvertView() to use VSplit for flexible vertical layout

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)

Updated the convert menu to default to source aspect ratio instead of 16:9,
which better preserves the original video's aspect ratio by default.
Changes:
- Initial state default: 16:9 → Source
- Empty fallback default: 16:9 → Source
- Reset button default: 16:9 → Source
- Clear video default: 16:9 → Source
- Updated hint label to reflect new default
