The recent update seems to have fixed my biggest bug - like bare minimum broken app... It wouldn't 'paint' when you switch windows and back; it was just a grey block of nothing, would have to zoom in and out to see the graphics. Doesn't happen anymore, also make sure 'use graphics processor' is on.

But to be fair I think the object selection tool is pretty cool and somewhat new & 'innovative.' though still lags behind. AE has had roto for a while and some basic ML you can find online has better feature detection. Still cool to see them heading in this direction having good edges would save a ton of time.
