Thanks for the link!
First, I love that this software is compatible with Freemind. That's the best selling point so far for me. I would probably never create a mind map on my BB, but importing one from Freemind, and viewing and making minor edits would be really nice.
One thing I would LOVE to see is integration with tasks. I don't use the native task application on my BB, I use Nozbe (online, GTD) instead, but the BB app would also work for this purpose:
I'm a software developer, and a novelist in my spare time (as yet unpublished). When I'm creating a new piece of software or a new story, the first thing I do in either case is mind map. As the map gets fleshed out, it invariably creates action items. It would make my life a LOT easier if I could click on an item and "Send to task list".
If that one thing were added, I would buy this software. As it is right now, it would be more of a toy than a tool.
