Arranging information by rank or in tree structures has become second nature for people who work on computers, so it makes sense to use an outliner that manages data in this way. Cherrytree [1] is essentially an editor that lets you structure text extensively with images and hyperlinks.

Cherrytree uses "nodes" as the essential management unit for all information. Nodes "collect" snippets of information and serve as anchors for branches. Although nodes have names, like headers in documents or memos, they have nothing to do with the name of the document. Your document is not named until you save the tree for the first time via File | Save or Save As. Before saving, you need to set the file format of the document (Figure 1). Typically you will use a SQLite database as the document type because it loads quickly and can be edited easily. Although you can password protect files, you should treat this function with caution: When an encrypted document is opened, Cherrytree creates an unencrypted version in /tmp/ that is used for editing. Cherrytree supports auto-save, which is activated in the Preferences dialog.
