Desktop panorama is an award-winning virtual desktop environment that uses the innovative concept of a linear virtual desktop. Unlike traditional virtual desktops like the ones seen in Linux desktops, the virtual desktop area is represented as an infinite stripe and windows can be freely moved around it. The advantages of this type of virtual desktop are that it gives you greater overview of open windows (the entire virtual desktop content is visible at a glance) and moving the windows around and onto the virtual desktop is also simplified and is done by dragging them with a mouse. Changing the view (the desktop) is done by selecting an area on the stripe using a mouse. Traditonal desktop switching is also supported by defining shortcuts.
Desktop Panorama is shareware, you can free download and try it for free during trial period. After that you may buy it for $15 or should delete it.
