Type of Enhancement

Server Backend

Describe the Feature/Enhancement

Support for Kepub file format for Kobo devices

Why would this be helpful?

This is the only file I keep my ebooks in due to features that aren't available in the normal epub format. Support should be trivial and fairly easy to maintain.

Future Implementation (Screenshot)

This would appear no differently from any other file.

Audiobookshelf Server Version

2.29.0

Current Implementation (Screenshot)

This is a purely backend implementation, other than minor updates to documentation and UI.

Do these files work with regular epub ereaders? If you rename the file extension and scan it into Abs does it work?

They're SOMEWHAT backwards compatible, if you open them with a .kepub.epub file extension, they work just fine, kobo devices can access the different structure within, but the epub readers ignore that portion and just keep reading as normal, but renaming all files will cause some issues for me at least.
If there's a way to pass the file to the epub reader as a .kepub.epub file, that would solve all that. I'm working out how to use kobo sync like Calibre-Web does, but I'd have to get back to you on that if I ever can get it working.
