Personal information manager and Python IDE, innovative authoring and programming tool.
Leo is an open source text editor/outliner that features clones (virtual copies of outline nodes) as its central tool of organization, navigation, customization and scripting.
Conceptually still the most advanced. Pity for the not so sexy GUI
super feature rich, and python integration
It's scriptable, integrates well in almost any environment
