FreeMind - Mind Mapping
FreeMind is project of the month on SourceForge. FreeMind is a very simple to use mind-mapping program, or a tree editor. One of my favourite features is that it can be almost fully controlled via the keyboard. I see that their is also a PDA application FreeMindPDA which is able to read and write FreeMind's XML files. The PDA version is a rewrite using SuperWaba, an open-source software development platform for PDAs.
