The Screen Shade

The Screen Shade is just what the name suggests.  Just as you can pull a shade over a window to block your view of what is outside the window, you can use the Screen Shade to block what is on your workspace.  By clicking and holding on the round buttons on the edge of the shade, you can lower the shade, or pull it across.  You can even lower the shade part way, the pull the shade across part way.  This is very similar to using a piece of paper on an overhead, but you don't have to worry about the paper falling off and revealing your information to soon!
