I just added a new feature I think is neat. When one part of a comment thread ends and the next comment is a reply to an earlier comment now there is an up arrow icon you can hover over to see a bit of the parent comment. Now it should be much easier to understand what people are talking about without having to collapse all the comments along the way.
Little easier to understand with a picture:
You must log in or # to comment.
Love all the additions!
That’s the kind of feature I never knew I needed, but when I see it in practice, I wonder how I ever lived without it.
