Doesn't the "jittery" thing from cropping only come about if you didn't set the origin points first? Shouldn't it go
1) Import all images (lets say they are all 128x128)
2) On any frame, position the Origin point.
3) Right-click the "Origin" point on the little floating window and click "Assign to whole animation"
4) Hold SHIFT and click the Crop icon.
5) ???
6) PROFIT
Tekniko , I kinda disagree that they add "more features over quality features". I think it happened a lot in the early days, which is shown by the fact that the image editor is a bit "eh" (I'm aware that c2 shouldn't be an image editor, but there's a few issues with the GUI), but as time went on and newer features got added, more quality was put into them (SpriteFont is awesome, Multiplayer is awesome, ect). Things get addressed pretty well, it just requires good reason.
