you are saying the essential of it. The idea of action/anti-action scheduling. 
All actions will 
have a anti-action counter-part, and a stack will save objects instead of 
deleting them.

for example (pseudo-code)

A clip c1 is deleted. instead of "delete c1", there will be 
"undo_push(c1,MustuxAction::DELETE_CLIP)"

if a undo is performed, there will be a call

MustuxObject ob = undo_pop();
MustuxAction ma = ob->get_action()
MustuxAction m2 = MustuxAction::get_anti_action(ma);
jmb_process_action(m2,ob);


it is brute code, but it can show the general idea.
