I would love the ability to group things to mind map nodes.
I have a giant tree of ideas, and if I could attach photos to the leaf nodes it would make it much more accessible. I can add photos and stickies now, but of course they remain in place when I move the node they are describing.
I wouldn’t need the mind-map code to organize its spacing based on grouped items, I can do that myself, but just having the ability to attach items to a mind-map node would open up a whole new way of using the feature.
for your consideration,
