I have a first working proof-of-concept of a Undo/history system, but it's still buggy and unstable, and besides I'm not sure it's the best way to go. It has the advantage that it doesn't need too many changes in existing code, as it tries to reshape a bit and use parts of code that are already there. The downside is that it uses a rather "rough" concept, saving states of the project object in a stack serializing them with cPickle, so restoring the previous state is not faster than light, but it works. I'm sure it can be done a lot better than this, so I hope that someone more experienced than I am can review my code and see if it is worth working on it or if it is totally dumb.
