Our main focus is currently on the iOS version. It will be released for users this autumn. Ok, the reader already works, and I'm reading my books on my iPhone. But some important features are still missing, we want to release a more or less complete version.
Another line of activity is related to the Book Network. Book metainfo editing and synchronisation, custom shelves in web interface, OPDS catalogs sync, multiple books operations, etc.
As for the reader itself, our next steps are Goodreads integration an more bookmarks/notes features. Some reading statistics might be added as well.
