ThinkTank (ver 2.41) Commercial made Abandoned Freeware ThinkTank is a character based "Outliner". An Outliner allows text to be organized into discrete sections that are related in a tree structure or hierarchy. Text may be collapsed into a node, or expanded and edited. Outliners are typically used for creating lecture notes, computer programming, collecting or organizing ideas, personal information management, and project management. MindMappers (and to some extent Wikis) are advanced extensions of how Outliners organize information. Although now owned by Symantec, Symantec has given permission to use ThinkTank for free, as long as you do not contact them for technical support.
