This is relatively minor but if it's easy to do, I think it would be helpful.
Small icons appear above the post titles in viewing posts in a forum. Would it be possible to show the arrow icon ("There are new posts. View first unread post.") first, to the left of the other icons? Right now, the person icon ("You've posted on this topic.") appears to the left of it, when they both appear. I think the arrow icon is more important and should catch the eye first. It used to be on the left in the old forum format.
