I would like to order discussions to show first (or only) those which doesn't have a reply at all. I mean, if you go to a community, you can filter discussions by "Open questions", but that doesn't means that the question has no replies, most of them has at least one or two, and if the discussion owner didn't mark it as Answered, it's still open. This isn't useful when looking for unanswered questions.
There's a way to do that? Any tips from anyone? Should I raise an Idea?
