1. Swipe actions appear to be using legacy vibration, instead of modern haptic feedback.
2. Personally, I think the community and instance list should be pages, instead of bottom sheets.
3. Community and instance pages should not be part of the home page, in my opinion.
4. Bottom sheet swipe-down always requires two swipes, no matter how fast the user performs it.
5. Bottom sheet gesture bar is not transparent. It should always be transparent.
6. Top sheets doesn’t go through the status bar. Again it should always be transparent.
7. Load spinner and confirmations should not be bottom sheets.

Edit 1

\8. Use modern keyboard animation instead of that old one from gingerbread or something.
