[What's left to do]

Glad to hear things are moving forward with your arm. I hope everything will be alright again soon.

What I'd like to have soon is the ability to export all frames (including inbetween frames) as a png sequence, not just the keyframes. Other than that my main wish would be deformation like the puppet tool provides in After Effects. That would be most useful for me. I know that's already planned, just wanted to +1 that.

A rather simple one which I think would enhance the workflow greatly: Let us pan the screen space by holding down the middle mouse button. I'm not sure if I just missed something but it doesn't seem to be supported, which makes for some unnecessarily clunky controls I feel.
