Tomboy is a desktop note-taking application for Linux and Unix. Simple
and easy to use, but with potential to help you organize the ideas and
information you deal with every day. The key to Tomboy's usefulness
lies in the ability to relate notes and ideas together. Using a
WikiWiki-like linking system, organizing ideas is as simple as typing
a name. Branching an idea off is easy as pressing the Link button. And
links between your ideas won't break, even when renaming and
reorganizing them.
