Self-explaining name. This application is your computers equivalent of a sticky note. Once this application has been opened, I recommend go to it's icon on the dock, right click and click where it says "open at login." You can do this with any application, and when you start your computer the application will open. In this case, your sticky notes will stay on your desktop for the next time you use the computer.

You can change the color of the sticky note, but you only have six options. You can also change the font, it's size and color.

It's a very useful application. Simple too.
