MiRO92/uYou-for-YouTube ? reverse-engineered prompt

Build me an iPhone YouTube tweak that makes the app feel way less annoying and more useful.

I want ads removed, videos to keep playing in the background, and a way to download videos, shorts, and audio for offline use. It should also have a built in media player for downloaded stuff, with background playback and easy export to the Camera Roll or Music app. Add simple controls for things like hiding or rearranging tabs, turning off autoplay and captions, looping videos, changing playback speed, and using gestures to control volume, brightness, and scrubbing.

Please also include Control Center playback controls, auto fullscreen, two finger tap play and pause, HD on cellular, and a cleaner iPad layout if that makes sense. Make it work with modern YouTube versions on iOS, and if you need current setup details, look up the latest docs online.
