Organizes and stores text in a tree structure

'TreeLine' organizes and stores text data in a tree structure. It is well suited to keeping track of many different types of information. Each node of the tree can contain several defined fields, forming a mini-database. User can define the format of each node; output can be shown on screen, printed, or exported to HTML. The tree structure is navigated and edited in the left pane of the window, while various views of the child data are shown and editable in the right pane. The data is stored in XML text files.
