[Feature suggestion] Add another column view mode

[Beanux]

Hello

Yet another feature suggestion (to add more work).

Recently i've been reading some cbz, cutting picture in half.

And i was wondering if there was a way to make something like an infinite scrolling mode. Or more reasonable a "triple page mode", showing the previous picture above , and below the next one.

And i didn't mention, it, but thanks for your work :)
