Hey, after trying every lemmy android app I could find, I like thunder the most other than Sync. But there are three main things that stop me from fully switching from Sync.

1. Option to hide bottom navigation bar on scroll, same as we already can with the top one.
2. Option to change the three dots on every post to a share button, hold for options or have both. I only ever vote, share (to save to read later) or check comments. That one extra step to save to my read later app gets weirdly annoying very quickly.
3. Compact card mode, looks the same as cards but have the smaller thumbnails to the side like compact does (which side as an option, right would be my choice).

Sorry if anything is badly explained, got no sleep last night so my brain is running on fumes, just ask if needed and I'll try to explain better.
