A desktop wiki and outliner Zim brings the concept of a wiki to your desktop. Store information, link pages, and edit with WYSISYG markup. Creating a new page is as easy as linking to a nonexistent page. Pages are stored in a folder structure, like in an outliner, and can have attachments. This tool can be used to keep track of TODO lists or ideas, to take notes during a meeting, or to draft any other kind of text (blog entries, important email, etc.).
