This feature was one of the most convenient things I’ve ever experienced in any app ever. It’s one of the reasons that Apollo was so endearing to me and others I’m sure. And I’ve never seen any other app that does it. If there is any way this could be implemented it would elevate Memmy above all others.
The problem is that a post is only marked as read once I vote on it or open it. Apollo recognized that I read it once I scrolled past it.
