You are a _genious_!
Nested undo... so i can decide to undo the undo stack... and maybe i can
create a stack for all undos wich in turn can be undone... mmh....
(noise of rotating gears)
However i agree: is a very cool thing, but you'd need something like a
standard undo function upon it.
The stack undoes on the 'model', the undo function undoes the stack.

Yes, but the effects may get very interesting (or very confusing... the two
things don't even exclude each other...)
It is definitely worth the effort.
