I agree with your point about the library. Maybe I'm just weird, but typically I'll read one, MAYBE two books at a time before moving on to another. Because of this, I really don't need the app to show me my library like this every time because its not like I'll be hopping around between books several times within an hour. I can see how this library setup makes sense for a music player or some sort of gaming platform, but it feels like for books they're just bringing the feature along without considering whether or not it makes sense. I guess it is nice to be able to gaze upon your library and think "wow I've read a lot" or "wow I have a lot of options to read", but I"m not sure I'd say that's worth the start up time.
