@caterpillar Thanks! It's used by a few hundred instances now, most notably Vivaldi's.
After leaving Twitter, I just wanted to bring back that 2019 feel. Some UI and UX patterns have already been proven to work, and it's great (unlike Twitter was) Mastodon is open source so I can customize it.
I've also submitted some suggestions to the core, since the only thing I'm still missing is the compose box, the rest I've built into my fork.
