This program simulates 100% Post-It for monitor. So you no longer need any real Post-It yellow paper on your monitor. You just write down what you want to remember on this program paper which can also be set to display on top of any other running programs. Right mouse button activates the pop-up menu where you can customize the paper options such as font, paper size, paper color, and text color. There is no limitation on which color you can use for paper and text colors. You can choose from among 16 million colors provided your system supports it. The paper can be dragged anywhere on the desktop by using the left mouse button.
