How does it work? It's simple; you just hide them in a sidebar. The application can show a thin color line on one side of the screen (preferably a bright color), so you can open all your notes just by clicking on it.
Apart from that, you can use this application as a launcher for other apps, adding as many shortcuts as you want inside the pullout bit. These can be opened with just one click, right from the launcher.
mfNotePad is an excellent tool to keep dozens of sticky notes and shortcuts right at the tip of your mouse without cluttering up your desktop and making it look ugly.
