I'm really interested in learning more about how use use FreeMind. I've been using a collection of text documents as "cheatsheets" that I can refer to, but it's less than perfect.
I used to have cheatsheets also (see here for the last version[1]), but I end up never use it because Google is simply faster . . .
I'll probably write some lines on FreeMind in a future post :)
Freemind looking OK on Ubuntu 12.10 with stock Unity desktop. I've just downloaded freeplane 1.2.20 from freeplane.org as the version in Ubuntu repos is 1.1.3. Looks nice with useful additions to the mind map. Seems to run OK with the same java and libraries as were installed for freemind.
Do you have other java based software installed? Does that look ok?
