I was wondering if it could be possible make a horizontal reading rather than vertical, in which we could ask to either read original style (right to left) or western style (left to right), it would work the exact same way (rolling the mouse wheel or using the arrow keys).
I would make reading a tiny bit more like reading a book, just for the experience

it would be particularly useful for wide screens (22" and above)

secondly, could you allow us to change the attributed keys, I have a 7 button mouse, with 2 under my thumb, which I would love to be able to use instead of B and N ... so I could read my manga without having to constantly press my keyboard
