We just pushed out the first public beta of a new mind mapping app with the aim to make it the most productive mind mapping canvas out there. We're planning to properly opensource the code soon. We'd love to hear your feedback on how to improve it.

Just wondering what you are using to connect the nodes. Is that all done with kinectjs?

Yes, it's all KineticJS, we developed a custom shape for connecting nodes.

Thanks. I liked it, Their should be visual buttons to do what the keys do. Unless there are and i'm just blind. It would also be nice is if you double click anywhere it creates a node that you can then connect to another node.
