Cool Desk is a virtual desktop manager. Ever wish to have several screens
on your computer? Cool Desk creates up to 9 virtual desktops and allows
you to have different windows in each of them. The desktop manager window
has a skinnable interface and allows you to switch from one desktop to
another with a single mouse click. You can easily minimize, maximize, close,
move from one desktop to another and even drop windows to the system tray
area (near the clock) using the dockable "Windows manager". Customizable
hotkeys help you conveniently manipulate your virtual desktops. Drag you
favorite applications and shortcuts over a specific virtual desktop icon to
open it there. Each virtual desktop can also have its own wallpaper. Cool
Desk supports multilingual interfaces.
