Added advanced audio channel remixing features for videos with imbalanced
left/right audio channels (e.g., music in left ear, vocals in right ear).
New audio channel options using FFmpeg pan filter:
- Left to Stereo: Copy left channel to both speakers
- Right to Stereo: Copy right channel to both speakers
- Mix to Stereo: Downmix both channels together evenly
- Swap L/R: Swap left and right channels
Changes:
- Updated audioChannelsSelect dropdown with 8 options (was 4)
- Implemented pan filter logic in all 4 FFmpeg command builders:
- buildFFmpegCommandFromJob (main convert)
- DVD encoding function
- Convert command builder
- Snippet generation
- Removed unused "os" import from internal/convert/ffmpeg.go
- Updated DONE.md with audio channel remixing feature
The pan filter syntax allows precise channel routing:
- pan=stereo|c0=c0|c1=c0 (left to both)
- pan=stereo|c0=c1|c1=c1 (right to both)
- pan=stereo|c0=0.5*c0+0.5*c1|c1=0.5*c0+0.5*c1 (mix)
- pan=stereo|c0=c1|c1=c0 (swap)

In Progress Tab Enhancements:
- Added animated striped progress bars to in-progress jobs
- Exported ModuleColor function for reuse across modules
- Shows real-time progress (0-100%) with module-specific colors
- Progress updates automatically as jobs run
- Maintains consistent visual style with queue view
Lossless Quality Preset Improvements:
- H.265 and AV1 now support all bitrate modes with lossless quality
- Lossless with Target Size mode now works for H.265/AV1
- H.264 and MPEG-2 no longer show "Lossless" option (codec limitation)
- Dynamic quality dropdown updates based on selected codec
- Automatic fallback to "Near-Lossless" when switching from lossless-capable
codec to non-lossless codec
Quality Options Logic:
- Base options: Draft, Standard, Balanced, High, Near-Lossless
- "Lossless" only appears for H.265 and AV1
- codecSupportsLossless() helper function checks compatibility
- updateQualityOptions() refreshes dropdown when codec changes
Lossless + Bitrate Mode Combinations:
- Lossless + CRF: Forces CRF 0 for perfect quality
- Lossless + CBR: Constant bitrate with lossless quality
- Lossless + VBR: Variable bitrate with lossless quality
- Lossless + Target Size: Calculates bitrate for exact file size with
best possible quality (now allowed for H.265/AV1)
Technical Implementation:
- Added Progress field to ui.HistoryEntry struct
- Exported StripedProgress widget and ModuleColor function
- updateQualityOptions() function dynamically filters quality presets
- updateEncodingControls() handles lossless modes per codec
- Descriptive hints explain each lossless+bitrate combination
This allows professional workflows where lossless quality is desired
but file size constraints still need to be met using Target Size mode.

Features:
- New "In Progress" tab shows running/pending jobs
- Displays active jobs without opening full queue
- Tab positioned first for quick visibility
- Shows "Running..." or "Pending" status
- No delete button on active jobs (only completed/failed)
Implementation:
- Updated BuildHistorySidebar to accept activeJobs parameter
- Converts queue.Job to ui.HistoryEntry for display
- Filters running/pending jobs from queue
- Conditional delete button (nil check)
- Dynamic status text based on job state
UX Improvements:
- Quick glance at current activity without queue view
- Three-tab layout: In Progress → Completed → Failed
- Consistent styling with existing history entries
- Tappable entries to view full job details
This allows users to monitor active conversions directly
from the history sidebar, reducing the need to constantly
check the full job queue view.

Features:
- Add "×" delete button to each history entry in sidebar
- Click to remove individual entries from history
- Automatically saves and refreshes sidebar after deletion
Bug Fixes:
- Fix nil pointer crash when opening Convert module
- Fixed widget initialization order: bitrateContainer now created
AFTER bitratePresetSelect is initialized
- Prevented "invalid memory address" panic in tabs layout
Technical Details:
- Added deleteHistoryEntry() method to remove entries by ID
- Updated BuildHistorySidebar signature to accept onEntryDelete callback
- Moved bitrateContainer creation from line 5742 to 5794
- All Select widgets now properly initialized before container creation
The crash was caused by bitrateContainer containing a nil
bitratePresetSelect widget, which crashed when Fyne's layout system
called .Visible() during tab initialization.

Integrated history sidebar into main menu with toggle button and split
view layout. Added history details dialog with FFmpeg command copy.
Changes:
- internal/ui/mainmenu.go:
* Updated BuildMainMenu() signature to accept sidebar parameters
* Added "☰ History" toggle button to header
* Implemented HSplit layout (20% sidebar, 80% main) when sidebar visible
- main.go:
* Added "sort" import for showHistoryDetails
* Added showHistoryDetails() method to display job details dialog
* Shows timestamps, config, error messages, FFmpeg command
* "Show in Folder" button (only if output file exists)
* "View Log" button (only if log file exists)
* Updated showMainMenu() to build and pass sidebar
* Implemented sidebar toggle that refreshes main menu
The sidebar can be toggled on/off from the main menu, shows history
entries with filtering by status (Completed vs Failed/Cancelled), and
clicking an entry opens a detailed view with all job information and
the ability to copy the FFmpeg command for manual execution.

Added "Copy Command" button to queue view for running and pending jobs,
allowing users to copy the FFmpeg command to clipboard for manual execution.
Changes:
- internal/ui/queueview.go: Add onCopyCommand parameter and buttons
- main.go: Implement onCopyCommand handler in showQueue()
The handler retrieves the job, generates the FFmpeg command with
INPUT/OUTPUT placeholders using buildFFmpegCommandFromJob(), and copies
it to the clipboard with a confirmation dialog.

Implemented the foundation for FFmpeg command copy functionality:
1. Created FFmpegCommandWidget (components.go):
- Displays FFmpeg commands in scrollable monospace text
- Includes "Copy Command" button with clipboard integration
- Shows confirmation dialog when copied
- Reusable widget for consistent UI across modules
2. Created buildFFmpegCommandFromJob() function (main.go):
- Extracts FFmpeg command from queue job config
- Uses INPUT/OUTPUT placeholders for portability
- Handles video filters (deinterlace, crop, scale, aspect, flip, rotate, fps)
- Handles video codecs with hardware acceleration (H.264, H.265, AV1, VP9)
- Handles quality modes (CRF, CBR, VBR)
- Handles audio codecs and settings
- Covers ~90% of convert job scenarios
This infrastructure enables users to copy the exact FFmpeg command
being used for conversions, making it easy to reproduce VideoTools'
output in external tools like Topaz or command-line ffmpeg.
Next phase will integrate this into the Convert module UI, queue view,
and conversion history sidebar.

The queue Stats() method was grouping cancelled and failed jobs together,
causing cancelled jobs to be displayed as "failed" in the status bar.
Updated Stats() to return a separate cancelled count and modified all
callers (updateStatsBar, queueProgressCounts, showMainMenu) to handle
the new return value. Also updated ConversionStatsBar to display
cancelled jobs separately in the status bar.

- Increase striped progress bar contrast (light: 90→60, dark: 140→200)
- Increase fill opacity (180→200) for better visibility
- Increase progress bar height from 14px to 20px across both striped and standard bars
- Makes progress bars more visible and easier to read at a glance
The striped gradient now has much clearer distinction between light and dark
stripes, and the increased thickness makes progress easier to track visually.
Removed cancelRunningLocked() call from Clear() method.
Now 'Clear Completed' only removes completed/failed/cancelled jobs
and preserves pending/running/paused jobs.
Previously it was cancelling active jobs before filtering, causing
running jobs (like merges) to be removed from the queue.
Enhances screenshot module with comprehensive technical metadata display including audio bitrate, adds 8px padding between thumbnails for professional contact sheets. Implements new Player module for video playback access. Adds complete Filters and Upscale modules with traditional FFmpeg scaling methods (Lanczos, Bicubic, Spline, Bilinear) and resolution presets (720p-8K). Introduces configurable snippet length (5-60s, default 20s) with batch generation capability for all loaded videos. Fixes snippet duration precision by re-encoding instead of stream copy to ensure frame-accurate cutting at configured length.
