One feature that would not go amiss would be easier searching of the ground spawns. It's not entirely clear or intuitive that only unified search allows this, as I didn't think of it until I started writing this post. Further, it would be very handy to be able to get the content of books/pages, etc. This could, of course, apply to both ground spawn books and dropped books. I would imagine that, coding-wise, these would be different tasks, but it'd be handy. Especially with the ground spawns, it's a pain to find them in order to read them and figure out the back story they're offering.
