animated bounding boxes please?

if possible, I'd like to suggest a way to animate or shift around the bounding boxes to be able to sync up better with animations...

possibly a feature that would allow one to change the size of each individual player frame..

and one more thing... a feature that would allow us to shift by pixels either our sprites in the tile sheet or even in the object editor...

please, maybe possibly? thanks !
