I sometimes stick lots of post-its on my monitor that remind me of upcoming important tasks. This is looking rather messy and I was looking for an alternative. A note is that alternative. The freeware lets you add post-it like notes right to your desktop. You are free to chose a color for the note, setup an alarm with sound or change the font of the note. You are able to change almost everything The notes can be uploaded to a database to use them from more than one computer. (for example home and office pc)
You have two options to create a new note. First you can right click the A note icon and select new note or double click the icon which has the same effect. Another great feature is that you can make the notes transparent in windows xp and NT.
