Hi,
NSUndoManager has made undo-redoing very simple. and I enjoy it very
much. What I'd need to do additionally is to save document as well as
it's undo actions so that user can retrieve document back to original
states even though it's saved and reopened.
I have a naive idea that it might be possible to save NSUndoManager
object's contents itself instead tracing document's changes separately
with NSUndoManager. but NSUndoManager doesn't seem to allow access to
contents of its instance. Would this be possible? how if so?
