I am not sure of the logic of the position of the pages. They seem somehow missaligned.
I position a screen A in the middle of the viewport by scrolling. I switch to screen B. The initial state of this one is misscentered. I scroll screen B to place it in the middle of the viewport. I switch to screen A. I seems that the scrolling of screen B happened in both screens; now half of screen A is outside of the viewport.
This is very annoying, because I spend I lot of time scrolling, especially if I don´t have an apple mouse and I have to click on the scrollbar in order to scroll horizontally.
