A few feature requests and suggestions for improvement

[GD2021]

1. Trigger casting before starting the playback task, rather than after.
   (Note: This ensures users can select their device before the video actually begins loading/playing.)
2. Automatically trigger background search upon entering the details page.
3. Support video disk pre-caching with a configurable cache size limit.
4. Support image caching with an option to limit the maximum cache size.
5. Allow users to disable unneeded modules (e.g., IPTV).
6. Add a one-click toggle between TV and Mobile modes. Switching to TV mode should disable certain touch gestures to provide an interaction logic better suited for TV interfaces.
7. Support an "Intro Skip" (Skip Opening Credits) feature.
8. Long-press the play button to launch/externalize to an MKV player.
