VirtuaWin is an awesome open-source desktop manager that lets you move between virtual monitors by moving your mouse. It's open source, too, by the way, and compatible with Stardock's screen customization software. You can set it up to move your screen with the mouse, meaning an effective multiplication of your screen room (the standard is four, but you can have nine easily). Try it, it takes five minutes to download and install, and it will let you go from screen to screen with ease. You can set constant programs to take everywhere. Five @'s.

    It's free, simple (the standard setup will do fine for most everyone, you'll know if you need the other releases), and useful. Try it today.
