you all did some great work on this program! It is my first mindmapper I've ever used and... well: up to now I found no better one! For that and for making it available as OSS I have to thank you!
A short remark I have nonetheless: Do You think it could be possible to create an Mediawiki-extension like this one, but with the possibility to edit uploaded files online? I think something like live-access shouldn't be necessary, the file could be locked when someone else is editing it. Due to the fact You're using Mediawiki as well, You could demonstrate your program live at you homepage...
It would be great if you take my request into consideration! Thanks a lot in advance!
