VimOutliner's purpose is to give Linux users a fast and productive outliner in a reasonable timeframe.
The design manifesto of VimOutliner is easy and fast outlining. It has been designed so that you can outline as fast as you can think. Most of the credit for accomplishing that design goal goes to the Vim editor itself, which is so keyboarder friendly as to double the productivity of average "GUI apps", at least for those comfortable with its keystrokes.
