I finally installed this on my Kobo Libra 2. The UX is clunky but overall it works great. Very fast. Don’t need KEPUBS anymore as epubs render just as fast, where as that’s not the case on the stock software.

I finally got around to installing it as I got an xteink x3 and wanted to have cross device syncing back to my Grimmory server. Works great with OPDS and KOSync.

Although I miss using the native kobo sync where I could just add a book to my virtual shelf and have it auto sync to my device. OPDS seems very rudimentary in comparison, but it works nonetheless.
