Think we're going to give people the option to toggle pages — with a few 'items per page' options or infinite scroll. Both options will be speedy eventually.

Pagination would also help very much with randomised TBR challenges. I love the idea of them but unless there's a lot of filtering involved I can't use them because my TBR is over 1k books long. With pagination I could then calculate what page the random number would be on and would have fewer books to count through.

Optional setting would definitely be a plus, especially if you can set the amount of books it shows per page, like one sees in one's inbox, perhaps. (No? Just me? >>; Oops. 😂)

It does help with navigation on lengthy tasks of sorting (tagging all books from last year, etc) to be able to add a URL appendix of "page=6" instead of having to scroll through all over again if you restart, reload the page, etc.
Possible as a toggle or other optional setting?
