nice, I forgot about that ...
I also played with MM, the brain and others, but it never worked for me. Everytime I created some mindmap, I wanted it to have in UR, so that I could link existing info in UR to it. I ended up with having duplicated info in mind map and UR, at the end, I always deleted the mind map and just created simple "mind map" structure in UR. I wish we had some plugin that would display data like in ConnectedText or MindRaider
