There was a comment in the thread about the new region-based used rankings about the redundant information displayed when a region has no preview systems. A suggestion was to allow a configuration parameter to select either the active only or active+preview for display at any given time. I personally like having both there right on the same page, but agree that it's silly to have the redundant information when there are no preview systems. My current plan is to look into a way to quickly detect whether there's preview system data to display, and if not, just don't show those tables.
