There's no public API for directly accessing the stacks (undo and
redo), however you could do the following:
1 - Subclass NSUndoManager.
2 - Override the appropriate methods ( -registerUndoWithTarget:... and
-prepareWithInvocationTarget: ) and provide logging before calling
super.
3 - Return a shared instance of your undo manager subclass for the
desired window(s) via the -[NSWindow windowWillReturnUndoManager:]
delegate method.
Of course this doesn't help with the redo stack, just what's added
to the undo stack.
