Session: Video Screen Saver - Feature 2 (Video Scaling Options) - COMPLETED
================================================================================

CRITICAL FIXES APPLIED:

1. MODAL SHEET BUG - FIXED ✓
   Location: Video_Screen_SaverView.m:554-564
   
   Problem: Options window/modal sheet worked initially but stopped appearing 
   after System Settings had been open for a while. Intermittent failure.
   
   Root Cause: Reusing the same NSWindow instance caused the sheet presentation
   to fail after some time.
   
   Solution: ALWAYS create a fresh window in -configureSheet method. Never reuse.
   Pattern now: Check if old window exists -> orderOut -> nil -> create fresh
   
   ⚠️ CRITICAL WARNING COMMENT ADDED ⚠️
   Added prominent warning comment at lines 555-558:
   "DO NOT MODIFY THIS PATTERN UNLESS ABSOLUTELY NECESSARY"
   "Reusing the window causes the sheet to stop appearing after working for a while"
   
   Status: TESTED AND WORKING - User confirmed "Options modal seems to work"

2. FOLDER REMOVAL BUG - FIXED ✓
   Location: Video_Screen_SaverView.m:876-887
   
   Problem: When removing a folder from Source Folders list, the folder 
   disappeared from UI but videos from that folder continued to play.
   
   Root Cause: Playlist only reloaded if (self.isPreview), but in System 
   Settings context, isPreview is NO, so playlist never updated.
   
   Solution: Changed from conditional reload to ALWAYS reload playlist:
   OLD: if (self.isPreview) { [self stopAnimation]; [self startAnimation]; }
   NEW: [self loadPlaylistAndStartPlayback];
   
   Status: BUILT AND INSTALLED - Ready for testing

3. SCALING MODE NAMING - FIXED ✓
   Location: Video_Screen_SaverView.m:702-762 (Display pane)
   
   Problem: "Center" mode didn't show visible difference on user's 16:9 display
   with 2K DCI (1.9:1) videos.
   
   Solution: Renamed "Center" to "Stretch" to accurately describe behavior
   (AVLayerVideoGravityResize stretches video to fill, distorting aspect ratio)
   
   Final Options: "Fill Screen" / "Fit to Screen" / "Stretch"

FEATURE 2 IMPLEMENTATION SUMMARY:

Feature: Video Scaling Options (from features.md)
Branch: feature/video-scaling-options (current: feature/custom1)

Added:
- VideoScaling enum (Fill/Fit/Stretch)
- Popup menu in Display pane with 3 scaling modes
- UserDefaults persistence with key "videoScaling"
- Applied scaling via AVPlayerView.videoGravity property
- Maps to: AVLayerVideoGravityResizeAspectFill / ResizeAspect / Resize

Files Modified:
- Video Screen Saver/Video_Screen_SaverView.m (scaling popup, enum, persistence)

REMAINING FEATURES (from features.md):
3. Recursive Folder Scanning
4. Show Filename Overlay  
5. Volume Control
6. More Transition Options

NEXT STEPS:
- User to test folder removal fix
- Commit Feature 2 changes
- Choose next feature to implement

Session: Video Screen Saver - Feature 2 Debugging - FOLDER REMOVAL BUG FIXED
================================================================================

CRITICAL BUG FOUND AND FIXED:

**FOLDER REMOVAL NOT PERSISTING BUG** - FIXED ✓
Location: Video_Screen_SaverView.m:217-264 (loadPlaylistAndStartPlayback)

Problem: 
User removes folder from Source Folders list, closes Options, reopens Options
→ removed folder REAPPEARS in the list, like it was never removed!

Symptoms from logs:
- "Verified: 0 folders saved" ✓ (save works)
- "Loaded 1 folders from UserDefaults" ✗ (load returns old value!)
- Migration code kept restoring the old single-folder bookmark

Root Cause:
The migration code was checking: `if (bookmarksArray.count > 0)`
When user removed all folders → array became empty (count = 0)
→ Condition failed → Went to ELSE block
→ Migration code found OLD single folder bookmark (kVideoFolderBookmarkKey)
→ RESTORED it to new key (kVideoFoldersBookmarksKey)
→ Migration ran EVERY TIME array was empty, continuously restoring old folder!

The Fix:
Changed line 224 from:
```objective-c
if (bookmarksArray && [bookmarksArray isKindOfClass:[NSArray class]] && bookmarksArray.count > 0)
```

To:
```objective-c
if (bookmarksArray != nil) {
    // New format exists (even if empty array) - use it
    if ([bookmarksArray isKindOfClass:[NSArray class]] && bookmarksArray.count > 0) {
        // ... load folders ...
    }
    // else: empty array means user removed all folders - don't migrate!
} else {
    // New format doesn't exist at all - try migration from legacy single folder
    // ... migrate only if new key is nil ...
}
```

Now:
- If new key exists (even as empty array []) → use it, DON'T migrate
- If new key is nil (doesn't exist) → migrate from old key ONCE

Result: Folder removal now persists correctly! ✓

DEBUGGING PROCESS:
1. Added extensive NSLog statements to track save/load
2. Discovered: saves verified as 0 folders, but loads returned 1 folder
3. Suspected ScreenSaverDefaults caching → tried NSUserDefaults direct write
4. Still failed → realized System Settings creates multiple view instances
5. Examined logs carefully → noticed timing of when folder reappeared
6. Found migration code was running after every save of empty array
7. Fixed condition to distinguish between "nil" and "empty array"

Additional Logging Added (can be removed later):
- Line 884-888: Before/After removal logs
- Line 903-918: Save verification with dual defaults check
- Line 571: Load from UserDefaults log
- Line 951: closeConfigSheet log

NEXT STEPS:
- Remove debug NSLog statements before final commit
- Test all folder operations (add, remove, multiple folders)
- Commit Feature 2 implementation

FILES MODIFIED THIS SESSION:
- Video Screen Saver/Video_Screen_SaverView.m (migration logic fix)

Session: Video Screen Saver - Feature 3 (Recursive Folder Scanning) - COMPLETED
================================================================================

FEATURE 3 IMPLEMENTATION SUMMARY:

Feature: Recursive Folder Scanning (from features.md)
Branch: feature/recursive-folder-scanning → merged to main
Status: TESTED AND WORKING ✓

User confirmed: "yes, works"

Implementation Details:

1. UserDefaults Integration
   - Added kRecursiveScanKey constant
   - Default value: NO (disabled by default for backwards compatibility)
   - Lines 24, 108: Key definition and default registration

2. UI Components
   - Added recursiveScanCheckbox property to interface (Line 53)
   - Checkbox positioned in Source Folders pane at (200, 10, 190, 24)
   - Lines 735-741: UI setup in setupSourceFoldersPane

3. Recursive Scanning Logic (Lines 486-564)
   - Updated getVideoURLsFromFolder to support dual modes:
     * Recursive mode: Uses NSDirectoryEnumerator for deep scanning
     * Non-recursive mode: Uses contentsOfDirectoryAtURL (original)
   - Properly skips directories when recursing (only processes video files)
   - Error handling with errorHandler block that continues enumeration

4. Settings Persistence
   - refreshUIFromDefaults: Updates checkbox from UserDefaults (Lines 856-858)
   - recursiveScanCheckboxClicked: Saves state and reloads playlist (Lines 993-1004)
   - Live updates: Immediately reloads playlist if screensaver is running

BENEFITS:
- Users can organize videos in nested folder structures
- Automatic discovery of videos at any depth
- Backwards compatible (disabled by default)
- Live updates when toggling

FILES MODIFIED:
- Video Screen Saver/Video_Screen_SaverView.m

Session: Video Screen Saver - Feature 4 Enhancements (Glass Effect) - FAILED
================================================================================

GLASS EFFECT IMPLEMENTATION - DID NOT WORK:

Branch: feature/filename-overlay-enhancements
Location: Video_Screen_SaverView.m:1374-1429

ATTEMPTED FIXES:
1. Changed NSVisualEffectBlendingModeBehindWindow → NSVisualEffectBlendingModeWithinWindow
2. Changed NSVisualEffectMaterialHUDWindow → NSVisualEffectMaterialContentBackground
3. Fixed text truncation with proper text field height calculation
4. Added subtle black tint (15% opacity) for contrast

RESULT: Glass effect still not working - no frosted/blurred background visible

ISSUES ENCOUNTERED:
- Initial build created arm64-only binary causing "arch mismatch" error
- Rebuilt with ONLY_ACTIVE_ARCH=NO to create universal binary (arm64 + x86_64)
- Video now shows up but glass effect remains non-functional

STATUS: Glass effect feature abandoned for now - not working as expected

FILES MODIFIED:
- Video Screen Saver/Video_Screen_SaverView.m (lines 1374-1429)
- Added imports: QuartzCore/QuartzCore.h, CoreImage/CoreImage.h
- Added UserDefaults keys: kFilenameFontTypeKey, kFilenameOpacityKey, kFilenameGlassEffectKey
- Added FilenameFontType enum
- Added UI properties: filenameFontTypePopUpButton, filenameOpacitySlider, etc.
- Increased config sheet window height: 350 → 550

NEXT STEPS:
- Commit current changes as-is
- Glass effect may need different approach or may not be feasible with AVPlayerLayer
- Continue with other features
