A 'virtual screens' or virtual desktops' manager. The program allows you to have a slew of programs open at one time without cluttering up your desktop or the taskbar. You can specify a screen for your word processing tasks, programming tasks, internet browsing, so on and so forth. Whatever window is opened in the current screen will disappear when you switch to another screen. Unlike in other virtual screens programs, the window disappears from the taskbar also! Furthermore, each screen has its own 'QuickStart' toolbar, a handy alternative to the Start Menu where you can create shortcuts to your programs. You can move Windows from screen to screen, copy Windows to other screens, and specify which Windows will traverse all the screens, plus much more.
