In my travels through the interwebs I came across a free, open-source mind mapping application called
FreeMind. I haven't spent a lot of time with it yet, but it looks like it could be useful for a lot of Coverinos. The interface isn't real intuitive, so spend some time with the documentation (found under "Help" on the top) to avoid frustration. Also, the program requires Java to be installed in order for it to function. Most folks already have Java installed, and it's also free and readily available, so it's not a big deal.
