Adds a gradient to the top of the scroll bar when using transparency feature


This review is for a previous version of the add-on ( 

This extension doesn't add the gradient, it is a "Windows" feature. Look exactly at your window (any window) caption and you will see there is always such a gradient, not only with glass effects on. ;-) You cannot disable it.
