I totally agree with JD Gumby - all I want is a way to turn it off. Until that happens I have been using a different launcher altogether. I find it totally useless, intrusive and basically ends up being an ad supported feature. And since I purchase so few books from Kobo itself, even the books in the discovery bar are useless. Of course that is assuming that at some point they will fix it so that when I say I've read a book or am not interested in a book it will disappear from the bar.
So...just give me one thing...the ability to turn it off - then I will go back to tapestries.
