Cache UI Data

### Checklist - [x] I've checked that there is no other issue about this feature request. - [x] This issue contains only one feature request. - [x] The title of this issue accurately describes the feature request. ### Feature description **Thanks for this awesome implementation!** **Persistent UI Cache** Right now every time I open any list or folder (likes or albums), the app reloads from YouTube’s cloud. Could we cache each view locally and refresh in the background? That would make navigation instant. ### Why do you want this feature? - **Faster navigation:** Avoid repeated cloud fetches on every view, especially on slow or metered connections. ### Additional information _No response_
