This tool improves Adobe Photoshop interface by turning secondary windows (palettes, properties etc.) into "emerging" state. When you don't need them they are hidden off the screen, so you can use all the screen for designing. And if you need any of them, move the mouse pointer to the edge of monitor where it is hidden and it will appear. This improvement will make your work with Adobe Photoshop much more effective and pleasant. New working style seems a bit inconvenient at first, but usually it takes 1-2 hours to adapt. Then you start working much faster than before.
