Cactusus

Cactusus is a program developed as a replacement for "sticky notes" on your desktop. Just a text taking quite a little space and always staying on top. Notes can be dragged by mouse to desired place. For each note your can define comments and a "see also" remark. Comments are displayed in a tooltip of the note. "See also" remark may contain anything that Windows can understand and launch: doc file, web link etc.
