Hi, here’s a short feedback:

1. A more compact view for the timeline: Mlem does it perfectly!
2. Look and feel has a slight edge over all other apps I am testing - I didn’t I didn’t miss any on iOS!
3. Disappearing bottom bar is not good, but the idea is nice if instead of disappearing, it would minimize a la Safari address bar.
4. Jump to alphabet letter in the community list - maybe tapping the letter brings up an alphabet grid?
5. Icons are golden! Clean and funny.

Good job and bring it on!
