Alas, mind maps are the essence of Mind Manager, not OmniOutliner -- and now with MM 7, you can roll mind maps into outlines and back, which owns OO 3, IMHO. Although I own OO 3, since MM 7 I find it's much more fun to use both the maps and outlines interchangeably. My OO 3 collects dust, especially since all todo-like features are taken over by OmniFocus. The only good use of OO was the discount for OF -- and which was too small.
