[Enhancement Request] Optimizing space

[RayZ3R0]

I feel like the space could be more optimized. Currently there are 2 columns on both sides which I find unnecessary. The left and right columns could be merged into a single column. This will leave more space for the pages. It will be especially useful on some pages where the page is horizontal and not vertical (the scenes that combine 2 pages sometimes are usually one whole page on manga sites). It will also make it possible to add a 2 page mode.

I like the idea of having a 2 page mode it think its been requested before
