When I'm creating set of brush tips, I keep them in one canvas, where every one is separated in layer or group. This is more convenient method than having every tip in a separate file.

I would like to have a function, that will automatically export every layer/group to separate brush tip files. It works that way, that it names a tip from layer's name (or group layer's if it's in group), a window pops up for every brush tip, so I can adjust its spacing (and animation type if it's a group).
This would speed up thing, because now I have to do it manually - remove all layers except one, trim image to layer and then export.

Maybe it is possible to do it in Python?
