Hi unikron,
I don't know if it's in your TODO, but adding hotspots in animation would be nice. Basically something along the lines of having a list of hotspots and setting their location per frame. I saw that you added the ability for users to extend the animation editor, perhaps it can be done through that? I haven't really looked into it as it is not crucial at the moment.
Thanks!
PS 1.90's animation editor is really awesome so far!
