User blog comment:BertH/Layout and navigation updates coming October 3/@comment-3388044-20120920052409/@comment-3508190-20120920052838

According to the demo link BertH posted above

the changes to the global nav's width are purely cosmetical. All the menu items are in the exact same place as before. The menu space to left and right is unused.
