When clicking on a BOLDED post in the list of latest posts on "What's New," it normally takes me to the oldest of the posts I have not yet seen in that thread. From time to time, it takes me to the first post in the thread. This is a minor annoyance, requiring scrolling through the first page of a thread to get to the page list at the bottom, then clicking on the link to the last page, and then trying to spot the earliest post that I don't recall reading.
This is a MINOR annoyance, I would not call it a high-priority thing to worry about, mentioned for what it is worth.
