I have changed the behavior so that the pedal now scrolls a percentage of the screen (and added a setting so you can switch it back to % of page if desired). The only exception to this is the single page display in landscape orientation with the half page display. In that case, since the page is doubled in height, I use the page height which is double the height of the screen (this is essentially the same as how the autoscroll works now). For that mode of operation, I think that's more intuitive to use. I also discovered that some of my calculations with the automatic scrolling were using an incorrect screen size when using the tablet in landscape orientation. This meant you might specify that you wanted to scroll 20% of the screen, but it would instead scroll 20% of the height of the screen in portrait orientation (on my tablet, this meant the scroll was closer to 33% of the screen in landscape orientation). I'm fixing this bug, but I'm really hoping users didn't work around this and I'm now going to mess them up. It's obviously a bug though and I don't want to leave it in place.
