I would really love to see Map Explorer functionality like Mind Genius. Like Marker Index but for the tier 1 nodes and when clicking on it drills the map down to that node as if it was the main topic and removes everything above and beside it. It has to be quick and dynamic like Mind Genius's implementation. You can click each one on the list (the tier 1 nodes) and it instantly focuses the map on that node and clicking another one switches instantly. If you click the top one (center top) it goes back to focusing on the center topic which is normal view.
