And every one of them has just one tiny annoyance I can't let go.

E.g.
Connect: only left hand voting. I use my phone almost always in one hand and it's my right hand.
Liftoff: no auto-hide the bottom (quite big) bar.
Summit: post actions only available when in the post. (Like save or share.)

So stuff like this. They are not the end of the world, but y'know: better without them.

And the stutter on most of them. Annoying as hell.

Interestingly I quit using Voyager because the scrolling wasn't high frame rate, but maybe that was because I was using it on Firefox? Thunder is smooth for me.
