I don't like that when you use the "unread posts since your last visit" link, it takes you to the last post in the thread. Personally, I like the old system of some kind of color difference between old posts and unread posts. Sometimes there are several new posts and as it is now you have to scroll up to see them. Also, I'd like to see the original post remain at the top of all multi page threads, not just the first. Otherwise it can be difficult to stay on subject.
However, thanks again for all the recent work and listening to our concerns. The site has come a long way in a few days.
