This is a very quick addon which hides the shadow around the action bars at the bottom of the screen.
This shadow sometimes is very obvious with a "line" visible where it starts. It can be distracting for some people. This addon removes the window with the shadow and creates a much cleaner look.
This ghost line is most obvious in the dark and while moving. it shows up mostly as a semi-circle above your ability bars.
If you would like to compare on/off type /habs in your chat box. it will toggle between on and off each time.
