When you are laying out a new design for a web site, the last thing you generally want to do is create a ton of images for the layout. You might make a rounded corner or shadowed text in Photoshop, but that is wasted time if the client doesn’t like it or the website doesn’t turn out as expected.
Brightside adds actions to the corners of the screen in GNOME, such as switching virtual desktops and controlling the volume. You can even enable the screensaver and control the screen brightness on your laptop.
