It would be great to have the possibility to decide for each node if the following nodes should be in horizontal or vertical layout. That would make organizing much easier.
Well, it would bring some problem about the mindmap arrange. As you can see, the nodes in marginnote are arranged automatically. What kind of mindmap would you like to make? It will be better if you give me a draft about your ideal mindmap.
Oh YES !!
I would LOVE this - is how I use SimpleMind
