I would also like to chime in to say that a basic sort/filter would be really useful. Just stuff like, sort alphabetically or by file size, filter by video game/PDF/other, filter by OS for video games. Not just in bundle purchases though, I don't see a way to do this in my library either?
A search by title would also be nice if you're feeling fancy, or just being able to set the layout to see everything on one screen (with smaller/no cover images) would allow CTRL+F searching.
