Thanks for the feedback. Cool to find a user on Hacker News! That's something I hadn't considered. I personally felt it more satisfying to mark as read when the post flies out. But I agree that it can be inconvenient. Do you think an Undo button would help (not sure if you've tried the Outlook iOS app, but it does it really well)?

We have better sorting options in the web and browser extensions, adding them to our iOS and Android apps is prio though. I like the idea with unread at the top!
