Great Viewer !

Maybe catalog support could be extended to support catalog interchange with emerging standards, like OPDS: Open Publication Distribution System

A way to sync with Calibre (http://calibre-ebook.com/) would be a nice feature.

This review is for a previous version of the add-on (1.3.0.1). 

OPDS

Thanks for your review!

Some OPDS catalogs are already integrated, they can be reached via the ePub catalog.
