origin and image points of a sprite frame can be propagate to all others frames in the same animation using apply to whole animation ... so ok perhaps with 20 animations who have to do the job 20 times but the needed propagate feature already exists !
About editor sure it will be more easy to have paint features in C2 but i consider that dev priority must stay in features that can't be done by others programs. Of course if someone find a way to include a basic paint tool in C2 with a plugin that could be very interesting !
I have another requested feature about sprites ... just have a way to give the number of polygons "points" to use in the "guess polygon shape" function ... standard settings seems really be good for squares or really simple shapes ... but have to create 20-30 collision points for 100 sprites with different shapes stay really a very hard work.
As a image is always better than speaking ...
Standard "guess polygon shape" function (up) (a 5 years baby could "guess" better)
The work that must de done after (down) ...
