@JPEG I'm hitting some pretty serious stability issues with the last two releases to the point where I've mostly had to switch back to Amaroq. What happened? Mast was always a little bit unstable, but not dozens of crashes an hour unstable. Amaroq and Toot! work perfectly normally on the same instance (mine).
Also hit, once or twice a day, a nasty bug that is probably related to table cell reuse. It's difficult to reproduce, but under certain conditions, it's possible to end up endlessly scrolling through the same screen of toots.
