I have a habit of saving everything I download from the Internet or copy from an external drive to the Desktop. So within days, my desktop gets cluttered with application shortcuts and files. So much so that anyone can hardly view the wallpaper behind the desktop icons and files.
To manage this cluttering of desktop, I use Fences. It can group your icons and files on the desktop. Also after installing fences, you can just double click anywhere on your desktop and all your icons and files will disappear, thus allowing you to view the cool looking wallpaper and a clean look. Also you can customize the color and opacity of your fences. Labeling fences is possible for better grouping.
Also the fences will automatically scale if you change the resolution of your screen.
