You would tend to register undo action in the order they need to be *undone*,
but logically if you need to make changes in response to changes made
controller's states. You can
also use multiple managed object contexts with different undo managers, and
reconcile them later. What you specifically need to do will determine the best
approach.

wold say the best approaches are a 50/50 between bindings and glue. That is,
you could use bindings for content, but manually handle state, or use bindings
for state, and manually handle content. Doing both is probably an exercise in
