The Browse feature
is nice, though I find the term "Contributor" (as opposed to "Author") interesting, I suppose they didn't want to have to fiddle the language when they move to non-book material. Contributor is still an odd choice to my mind.
I'd also like to have an alphabet selector for the A-Z listing options instead of a numbered page thing, it's a bit cumbersome, and I don't want to have to do work that the computer can do for me so easily.
