It would be handy if all of the thread pages repeated at the BOTTOM of the thread the links for the current forum, parent forum and top forum. If you look at the top of this thread page, you'll see these links:
Bike Forums (top level)
News & Suggestions (child level)
Forum Suggestions... (grandchild level).
Repeating those links at the bottom (near the next/previous thread links) would be helpful. After I read a thread, I scroll to the top and click the parent forum link so that my read/unread threads will display correctly. (I like to hunt for unread threads). If you just backspace, the page does not refresh so you don't see what's new correctly.
