+#### 4.4.1: Mobile Gesture Support - COMPLETED 9/29/2025
+- [x] Add swipe gestures for chat toggling
+- [x] Implement pull-to-refresh functionality
+- [x] Create touch-based video controls
+
+**Notes:** Comprehensive mobile gesture system fully implemented. Swipe gestures on video area toggle chat on mobile (swipe left to hide, right to show). Pull-to-refresh functionality added with visual indicator showing on mobile when pulling down from top of page. Touch-based video controls include double-tap on video for fullscreen toggle and swipe gestures on tablets for seek forward/backward (10 seconds). All gestures are device-aware and won't conflict with desktop interactions.
