You can set it that doesn't suck out scene breaks and special margins.

I think mangling in KOReader is sort of optional. We plan on having native Linux, OSX & Windows app by Q1 2022. The bonus is that we also have native Android and iOS apps so you will be able to keep your highlights and reading progress synced across all devices. You could take the BookFusion Web app for a spin that will work on Linux and any other operating system. Just to mention, I have tried KOReader, Foliate, ePUBReader, Calibre eReader, FBReader, CoolReader… I'm looking at something able to render ePub files as close to the ADE does because I was told by Windows users that ADE is the standard app (?). I understand that no app does it completely. I would love to know which is the most accurate to the fullfill the standard. I always see so many differences between them with the same ePub file. I'm trying to use an app for ePub reading in Linux that best fullfill the ePUB 2.x standard (I mean that I'm not interested in ePUB 3).
