Hierachy Software

ActiveTreeNotes is a blazingly fast, very simple to use information organizer. Using a hierarchical metaphor (tree based), you can create and organize any kind of information, from websites, to ski resorts, to recipes, to writing snippets. The tree holds information in a hierarchy, with each folder being tied to a entry on the right. The entry has bold/italics/underline, plus other commonly used word processing capabilities.
