Intended for rooted Nook Simple Touch or GlowLight.
Should the screen become too grey because it has not been fully refreshed for a while, running this app will clear away the grey shadowing and give you a new fresh white background.
It can either be run from the Notification area where it sits permanently, or it can be associated with one of the hardware buttons, e.g. the upper right button. So if you are within your Kindle app, and the background has gone a bit grey, pressing the upper right button will clear the background to a pristine white.
