looks slick!! congrats! Is it similiar to MindNode on the Mac? I use that a lot and have been on the hunt for a great web-alternative with no success so far!
It can be used as a mindmapping-tool, yes. However, it's actually more a project management tool than a mindmaping-tool, so some features like change the color of a branch are not available but you get all those PM features instead (like a calendar, comments, file attachments etc).
