Looking at the Japanese lists, we’re up to 47 with no signs of slowing down. I was thinking more ways to filter lists would be appreciated; an easy one could be filtering lists by the type of media in them; i.e. you select the non-fiction checkbox to only see lists that contain non-fiction books (or click the box again to prevent any lists with non-fiction from showing):
Might also be nice to be able to designate a list a “book club” list (i.e., one that only lists either book club candidates or winners) so that users can filter to see only book club lists or none at all.
Being able to filter by which lists contain at least one Free book could be nice, especially if you wanted to sample from a couple of different ones but were on a budget.
Dunno how useful it would be, but being able to sort alphabetically by list title and number of list items (ascending and descending, of course) also feel like solid options.
