LightSwitch 1.2 - This package adds a small button to the backdrop application that lets you toggle the state of the backlighting on and off. It is very tiny and very fast and works well with the Power On Backlight control in PowerPrefs 2.0. Note that not all backdrop apps show auxillary buttons. If you install it on a Newton device without a backlight nothing happens.  If you install it on a pre-Newton 2.0 device it will probably display an error. You can install this on a card without getting the "Remount" message when you eject but be aware that the extension uses more heap memory this way.  Installed internally it uses less heap.
