Improvements
- Audio-only playback. A button in the player, or "Audio only" in the quality menu. No video segment is fetched, so it saves data; the choice is remembered for the session (#41)
- High-resolution thumbnails. The default is picked from your device's memory to keep scrolling smooth, and you can override it in Settings → Appearance → Thumbnail Quality, up to YouTube's full 1280×720 file (#37, thanks @PoomSmart)
- Device Info. About now shows your iOS version and device model, and every field there copies on tap (#43)
Fixes
- Fullscreen on iPhone. Fixed how the app handles a device that is already held sideways when a video opens (#39)
