The ultimate replacement for spreadsheets, mind mappers, outliners, PIMs, text editors and small databases. Suitable for any kind of data organization, such as To-do lists, calendars, project management, brainstorming, organizing ideas, planning, requirements gathering, presentation of information, etc. Its like a spreadsheet, immediately familiar, but much more suitable for complex data because its hierarchical. Its like a mind mapper, but more organized and compact. Its like an outliner, but in more than one dimension. Its like a text editor, but with structure.
