I'm not even sure if it's 3PA only feature but there's option to hide all posts that you've read (or scrolled past). After finding that feature now i want it everywhere there's infinite scroll because yeah otherwise it's unusable.

That feature's way less useful when you don't read each and every post in sequential order. Also sometimes I want to go back and look at something I've already read. That makes it complicated too.
