Make collaboration easier by better integration with the Google Docs collaboration tools
Presently it is a bit combersome to collaborate with the collaboration extension. It would be so nice if it could just work like with Google Docs: everybody who has permission can edit simultaniously.
One of the MindMup explanation pages states it nicely this way: "We have lots of interesting ideas for improving the collaboration workflow, and the end-game, we hope, is completely merging collaboration into normal google drive maps, so that collaboration requires no specific set-up or extension loading, and that collaborative maps no longer have the limits imposed by the Google Realtime API (10MB limit per map). This would also mean that all maps stored on Google Drive get auto-saved by default, which would make MindMup work a lot more similar to familiar Google Docs applications"
This feature will bring thousands more users in!
mindmup 2.0 is much better integrated with drive collaboration tools. see http://blog.mindmup.com/2015/10/mindmup-20-is-now-ready.html for more info
