I love that when looking at books read for a specific year or month I can sort by page count but would also really like it to be able to sort by length of audiobook. The way it appears now audiobooks usually show as low for pages read but in random order, but it would be nice for them to also be in order from shortest to longest. This could maybe be included in the current page sorting setting or have a second sorting option for audiobooks that sorts them by duration.
