Dim the screen
Great app and does as advertised so Im very happy. However, a feature that I think is essential is to dim the screen when the button is pressed. Sure, when its up to your face the screen is dim, but you may not want the screen to stand out at all as you are bringing it up to your face. There should be some type of masking happening.
Other than that request, I would say this is a must have.
