My favorite option coming from Boost is a Hide read button that hides all the posts I just scrolled through. This makes it very convenient to visit the front page again later - all posts and content are fresh.
Bonus option, hide Upvoted and downvoted.
As a previous Boost user, I concur. I really miss being able to simply hide the previously read posts and clean up my home feed. Connect is amazing so far, but this feature add would make things that much better!
