Freemind, the open source Java based mind mapping application, makes a great writing planning tool. A final release of version 0.9 has been a long time coming, but the current release candidates are very usable and stable, and I would recommend making the extra effort to install one of these rather than an 0.8 “stable” release. Fortunately, the 0.9 RCs have made it into the standard Ubuntu 10.04 repository.
