At least for me, on http://askubuntu.com, the top bar highlights the number of items in the "Suggested Edits" queue (whenever there's something to process).
However, the counter does not update after items are processed. First world problem: after processing the queue, I click it just to find "There are no items for you to review."
Obviously, it's really minor, but as almost everything on Stack Exchange updates automatically, that probably could too.
