ThumbWin: Minimize open windows to thumbnails
ThumbWin gives your minimized windows a bit more visual information. Once you install and run this tiny application, any time you minimize a window, a thumbnail will be created on your desktop. You can click the thumbnail to maximize a window, or click the close button on a thumbnail to exit a program.
ThumbWin only kicks in if you minimize applications one at a time. If you hit the show desktop button, no thumbnails will be created. The utility is highly customizable, letting you change the thumbnail dimensions and layout. You can also select certain programs to exclude from ThumbWin, which will prevent thumbnails from being generated when you minimize those applications.
