Why Would I Want To Do This?
One of my favorite features of the Mac OS X is the way it handles multiple desktops and manages the apps you have made full screen by placing them in their own desktop. Much like you can cycle through your running applications, it’s also very easy to manage and move between those desktops using Mission Control. By default though your Mac will include and show a desktop for your Mac Dashboard.
While Dashboard can be useful with the addition of a weather or note pad widget, Apple has really minimized its emphasis and my experience is that most folks don’t use it very often, if ever. If you’re one who either doesn’t use Dashboard or would just prefer to not have it appear as its own desktop or space, it’s really easy to disable it.
