Modules with handlers but missing dependencies now show orange
background with stripes instead of grey. This distinguishes them
from unimplemented modules (grey) and helps users identify what
needs to be installed.
Changed module colors to work better with white text:
- Trim: #FFEB3B → #F9A825 (dark yellow/gold)
- Audio: #FFC107 → #FF8F00 (dark amber)
- Subtitles: #8BC34A → #689F38 (dark green)
All modules now use consistent white text for uniform appearance.
The diagonal stripe pattern raster function was returning nil for
enabled modules, causing a nil pointer dereference when Fyne tried
to process the texture. Fixed by always returning a valid image -
transparent for enabled modules, striped for disabled modules.

Replaced lock icon-only approach with diagonal stripe overlay for better visual distinction:
- Added static (non-animated) diagonal stripe pattern to disabled tiles
- Stripes use semi-transparent dark overlay (similar to queue progress bars)
- Thicker diagonal lines (8px spacing instead of 4px)
- Pattern clearly distinguishes disabled from enabled modules
- Kept lock icon as secondary indicator
This addresses the issue where adaptive text colors made it difficult to distinguish available vs. disabled modules. The stripe pattern provides immediate visual feedback without relying solely on color dimming.

Enhanced disabled module visual indicators:
- Added lock icon (🔒) in top-right corner of disabled tiles
- Lock icon shows/hides dynamically based on module availability
- Improved Refresh() to handle dynamic enable/disable state changes
- Updated renderer to include lock icon in layout and objects list
This makes it immediately clear which modules are available and which require missing dependencies, addressing the issue where adaptive text colors made disabled modules less distinguishable.

Implemented automatic text color adaptation based on background brightness to improve readability:
- Added getContrastColor() function using WCAG luminance formula
- Bright modules (Trim/yellow, Audio/amber, Subtitles/light-green) now use dark text
- Dark modules continue using light text
- Ensures high contrast ratio for all module tiles
- Prevents eye strain from low-contrast combinations
This fixes the accessibility issue where bright yellow, amber, and light green modules had poor legibility with white text.

Redesigned main menu for better space efficiency and visual organization:
- Changed from flexible GridWrap to fixed 3-column grid layout
- Organized modules into priority-based sections with category labels
- Category labels positioned above each section (Convert, Inspect, Disc, Playback)
- Reduced tile size from 150x65 to 135x58 for better spacing
- Removed excessive padding for more compact layout
- All 15 modules now visible in organized 3x5 grid
Layout organization:
- Row 1-2: Convert modules (Convert, Merge, Trim, Filters, Audio, Subtitles)
- Row 3: Inspect/Advanced (Compare, Inspect, Upscale)
- Row 4: Disc modules (Author, Rip, Blu-Ray)
- Row 5: Misc modules (Player, Thumb, Settings)
This addresses user feedback about wasted space and provides a more polished, professional appearance.

Benefits:
- Better workflow when adding files during active conversions
- "Convert Now" truly prioritizes the current file
- No more broken partial files cluttering output directories
- Cleaner error handling and disk space management

Issue:
- Jake reported command prompts popping up during benchmark runs on Windows
- FFmpeg processes were showing console windows during tests
- Disruptive user experience, not discreet
Root Cause:
- exec.CommandContext on Windows shows command prompt by default
- Benchmark suite runs multiple FFmpeg processes (test video generation + encoder tests)
- No platform-specific window hiding applied
Solution:
- Apply utils.ApplyNoWindow() to all FFmpeg benchmark commands
- Uses SysProcAttr{HideWindow: true} on Windows
- No-op on Linux/macOS (cross-platform safe)
Implementation:
- Import internal/utils in benchmark package
- Call ApplyNoWindow() on test video generation command
- Call ApplyNoWindow() on each encoder benchmark test command
- Ensures all benchmark processes run hidden on Windows
Files Changed:
- internal/benchmark/benchmark.go: Added ApplyNoWindow() calls
Platform-Specific Code:
- internal/utils/proc_windows.go: HideWindow implementation (existing)
- internal/utils/proc_other.go: No-op implementation (existing)
Impact:
- Clean, discreet benchmarking on Windows
- No console windows popping up during tests
- Same behavior on all platforms
Reported-by: Jake (Windows command prompt popups)
Tested-on: Linux (build successful, no-op behavior verified)

Critical Fix:
- Goroutine dump showed hundreds of leaked animation goroutines
- Each queue refresh created NEW progress bars without stopping old ones
- Animation goroutines continued running forever, consuming resources
Root Cause:
- BuildQueueView() creates new StripedProgress widgets on every refresh
- StartAnimation() spawned goroutines for running jobs
- Old widgets were discarded but goroutines never stopped
- Fyne's Destroy() method not reliably called when rebuilding view
Solution:
- Track all active StripedProgress widgets in appState.queueActiveProgress
- Stop ALL animations before rebuilding queue view
- Stop ALL animations when leaving queue view (stopQueueAutoRefresh)
- BuildQueueView now returns list of active progress bars
- Prevents hundreds of leaked goroutines from accumulating
Implementation:
- Added queueActiveProgress []*ui.StripedProgress to appState
- Modified BuildQueueView signature to return progress list
- Stop old animations in refreshQueueView() before calling BuildQueueView
- Stop all animations in stopQueueAutoRefresh() when navigating away
- Track running job progress bars and append to activeProgress slice
Files Changed:
- main.go: appState field, refreshQueueView(), stopQueueAutoRefresh()
- internal/ui/queueview.go: BuildQueueView(), buildJobItem()
Impact:
- Eliminates goroutine leak that caused resource exhaustion
- Clean shutdown of animation goroutines on refresh and navigation
- Should dramatically reduce memory usage and CPU overhead

Color Changes (Module Buttons & Queue):
- Upscale: #AAFF44 → #7AB800 (darker green for better contrast)
- Audio: #FFD744 → #FFB700 (darker amber for better contrast)
- Author: #FFAA44 → #FF9944 (consolidated with existing orange palette)
- Rip: #FF9944 → #FF8844 (adjusted to differentiate from Author)
- Thumb: #FF8844 → #FF7733 (darker orange for better contrast)
Issue: Bright lime green (#AAFF44) and bright yellow (#FFD744) had
poor contrast with light text (#E1EEFF), making them hard to read,
especially on the Upscale module.
Solution: Darkened problematic colors while maintaining visual
distinction between modules. New colors meet WCAG contrast guidelines
for better accessibility.

- 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)
