The code, while amazing for its time, was buggy. Furthermore, clones were in fact *copies* of nodes, so updating an outline containing clones was very slow. Leo has gone through two or three major improvements to its data structure since those early. Now, *all *outline operations merely change python references (like changing C pointers). Leo's unlimited undo means that data is never actually garbage collected, which is correct. Feel free to discuss Leo on MacInTouch. Leo doesn't do presentations directly, but it does everything else far better than MORE did. And Leo (almost) never hard crashes, which could not be said for MORE.
