With the recent 5.16.2.1.1 jailbreak, I wanted to try out KOreader. Worked very well to get rid of margins, I could have text right up to the edges, but sadly, the renderer has no support for vertical text and doesn't look like it'll ever get it, so it's pretty much useless for most of my use cases.

The stock experience supports vertical formatting no problem, but has awful fat margins on all 4 sides, with top and bottom seemingly mandatory. Looking around I found some info about reducing these on much older hardware like the Kindle 2, but I can't find anything more recent than that. Negative margins through Calibre might help with the sides, but they don't help with all the wasted vertical area. Has anyone found a way to reclaim some of the screen without having to manually edit every book?
