MindManager, Requirements and Wikis
I think it's a good idea, but when I was trying it I felt that I was doing something similar to what I do when I start writing ideas on our internal Wiki in the sense that I have a tree of related documents, that can be represented as a set of Wiki pages, and in each leaf there's probably a document describing the feature. In their tool they have a text editor to create it, but it would be much better if it was a Wiki page.
On the other hand, is much easier to edit and visualize the mind map than a set of Wiki Pages.
It would be great if we can mix both worlds and have an editor for wiki pages lets you visualize them and edit them as a Mind Map. If someone knows of such a tool, let me know!
