Linux has some cool features, some of which I wish were available for Windows 7. A virtual desktop is one of those features. Virtual desktops allow you to have up to four different desktops at once. You can display different windows on different desktops. Each virtual desktop has its own windows and desktop icons.
When using a virtual desktop you can drag a window from one desktop to the other and switch desktops with the press of a button. WindowsPager allows a preview of each desktop in the task bar of your screen to provide you with easy navigation.
There are a few applications that provide this behavior in Windows, but I’ve found WindowsPager to do it efficiently. The other benefit to this software is that it’s not only free but open source.
What I wish for future versions:
The software can definitely be improved upon. With Linux versions of virtual desktop it’s possible to turn your desktop into a 3d rotating cube. You hit a key and the desktop will automatically turn into a cube. You can see three sides of the cube and use the arrow keys to navigate between them. I think combined with Aero, this would be an amazing feature for the Windows versions.
