Well, to me, substacks are like regular stacks, just without a separate 
on-disk representation. I usually use them for secondary windows, tool 
palettes, dialog boxes, etc. Groups/backgrounds are for sharing objects 
across multiple cards in a stack, so they really aren't very much like 
substacks, IMHO. Can you provide more info as to how you're viewing 
substacks/groups and what you want to accomplish?
