Thanks for the demo. The undo/redo system follows the Command pattern as well as the Momento pattern (for extensibility reasons). At the moment there is a ModelMomento class but there is no way of adding ModelMomento objects to the Controller. To implement undo/redo, you need to add commands which can then be popped off the undo stack and pushed onto the redo stack etc etc. The Undo/Redo system doesn work automatically.

Adding ModelMomento is a todo item.

This has now been addressed by adding the ModelCommand class and changing the implementation of the ModelMomento class. See updated example for implementation details.
