UndoManager for NSApplication

The problem with my situation is that the application might not have a window up as it has been deleted, so I can not use the NSUndoManager associated with the window system.

AFAIK, of the NSResponders only NSWindow creates its own NSUndoManager. Now, any responder on a window will automatically search up the responder chain for an undo manager, so it should automatically get the window's.
