In addition to the search bar for lists, it'd be great if there were better navigation options. This could look like one or several of:

a toggle to set the desired number of entries per page (10/30/100 etc)

adding a footer with number links to allow skipping to later pages (and showing where you are in your list)

a more text-based table view that minimises image size and shows more books per screen

(But please not infinite scroll which is horrible for searching 🙂)
