NOTE: version 2.0 is now out and it will add custom NODE themes so look for this version instead.
But, MindMUP is easy to use, links to google docs, can insert web links, images, and has color tools, and notes. Useful 'theme' patterns to give maps nice look/feel.
Things we'd like to see improved:
1. Ability to add "cross-links" between nodes with ability to ADD TEXT to them
2. Published Maps seem to give you ONE look at path/URL then can find them again? how to search Published maps for later use would be helpful
3. Would like ability to add text notes to lines that connect nodes!! Also very useful in science
4. Node notes is bit awkward to read as all of them open in side window when click any ONE note which can be overwhelming.
but generally a powerful, affordable tool that you can learn / teach others very quickly!
