I think that a really neat function that could possibly be added to the library could be a little reading nook, or something to that effect, where you can leave a pet to read the books you have in your library. 

Considering that there's been timers added to the game already via the new training option (granted, I know little to nothing about online/web coding) it does seem like something that could be feasible? I'm not sure exactly how it would or could operate, but my idea was basically this: 

-Choose a pet to leave in the library

-It counts the number of books you have, or if the pet has already read them, and generates a time

-that pet becomes unavailable during that time, like with explore and training

-When it's done it pings you that they're finished reading and it tells you how many books they read, possibly the increase in intellect

This could also possibly prevent you from adding books to your library during the time they're in the reading nook, to keep it from breaking

I'm sorry if this has been suggested before; I tried to go back as far as I could in previous posts and the log of past suggestions
