In the developer theme, threads with new posts are clearly marked, although you still have to scroll down to the bottom to find the new posts. That doesn’t seem very onerous to me.
What does bug me is that it seems to be necessary to go back to the index page after reading each thread in order to find the next one with new posts. When you’re reading a thread, at the bottom of the page are links to “next” and “previous” threads (not explicitly so labeled, but with double arrowhead marks pointing right for one and left for the other.
As near as I can tell, these refer to the order in which the threads were created, and are never updated to reflect the new ordering (based on most recent post) in the index. Unlike the “next topic” and “previous topic” links back at EZboard, these are almost perfectly useless, unless you’ve come to the board never having read any of the threads before, and don’t care if you get ones with recent posts mixed in with those that haven’t had anything added in days.
Is there anyway to change that function? It’s really more convenient to go from thread to thread directly instead of having to jump back up to the index between each.
