No UNsubscribe buttons
Here the user only sees ways to mark things as read,
but no way to rid them from cropping up again.
He even sees a watch button, but no unwatch button.
He desperately needs to see "Unfollow" etc. buttons.
He doesn't see a way to clear the mess from hounding him in the future months sometime again, and he doesn't see "you are seeing this because you did ..." etc.
