I agree with this post. I would love to be able to dim the display for night reading and not have to go back to settings to change the brightness. I've noticed some "flashlight" apps that have a brightness control. All of them seem to be able to dim the current brightness level but not make it brighter then is set in the "settings" app. Other than that perhaps a tweak of the turn page animation to better copy the way a page is really turned when reading a real book (this is a very minor critique). Overall though, a great app.
