One needs to concentrate to one’s thoughts when creating a MindMap. So, operation needs to be intuitive. No lines to draw. They need to be drawn automaticly! Thought’s need to be inserted one after each other, separated by ENTER key. Sub-Nodes (one hirarchy down) need to be inserted by ONE key, e.g. INSERT button.
Thoughts need to be arranged and connected by lines automaticly.
That would be implementation of a Mind-Map Tool. And that would realy empower prezi as creative writing and presenting tool!
Either importing mindmaps from Freemind, or integrating the whole freemind tool into prezi would help. Second choise prefered!
(FreeMind is OpenSource, so implementation into prezi should work easily.)
