I have a few other feature requests that I just discovere while trying to test this further.
I moved a book out of my Kobo.com archive to try it with a fresh kobo official book, and discovered:
1. there's apparently no way to access my archived books from the Kobo itself. That's a bit annoying. Why doesn't the on-device store have a way to view the archive and restore books?
2. when doing a sync, OS updates are forced right then and there -- while it was nice to see that there was an update, it was unfortunate to be forced to wait just because I did a sync to download a book.
(and lest I sound like a complainer, the new Overdrive feature is nice [though to stay on the topic of complaining

, it still only shows me one library, even though I'm logged into my Overdrive account])
The book that I just downloaded from my archive did start the TOC on page 1.
