Sprite Sheet Maker

[tombmonkey]

Suggestion:  Would it be possible to add in a feature to make Sprite with different sized boxes animate properly?  
Something like, "Resize boxes to largest Sprite size in the group", if that makes any sense.

It's the third button below the preview, "Balance/Resize Animation..."

Notice that if your sprites come from an atlas and when you extracted them you didn't account for the trimmed space, then the sheeter has no way of knowing the axis of each frame, and so it has no way to properly place the frames so the animation would play properly.
