I know that posts can be hidden by reading.
But what I miss most is a button to hide posts while scrolling over them, so that I don’t see the same posts over and over again.
(Boost for Reddit has a Button to “hide all previous”, so you don’t have to hide each post individually, but all at once)
Yes an option to mark as read when scrolling over a post. And then a button that can hide read posts.
That’s the way I’ve been using reddit sync.
