Add an option to select a preferred rendering engine for sideloaded epubs.
So a user is able to use either
1. the Kepub rendering engine
2. Adobe Digital Editions Mobile rendering engine (default setting)

Offcourse, a preference set by the user will be overruled if a sideloaded epub is protected with Adobe DRM, then Adobe's rendering engine will be used.
And yes I am aware that using the kepub rendering engine on sideloaded epubs has it limitations. Not all features of original Kobo kepubs are available (or will work properly) on a sideloaded epub.

But after reading this forum i learned that there are lots of users here that are interested using some features of kepubs (e.g. show book and chapter title, the number of pages of a chapter) but don't want it to do manually or let alone hacking their device.
It will enhance the user experience (features not offered by other competitor hardware vendors) and also ties the user to the Kobo eco system and may stimulate Kobo's book sales.
