Add a badge with # of pending requests to the "Requests" row in sidebar
I think it'd be a nice UI addition for admins to see the number of pending requests in a red badge next to the "Requests" button in the sidebar. Unless you're getting notifications, you wouldn't know there's a new request unless you go to the requests tab.
While I'm on the subject, having those badges present on the tab headers in the Requests page would be pretty slick, too.
V4 is looking awesome!
