I have requested this many times since Civ IV, but it's long past due time to truly support dual monitors. The world map should be on the left. A detail screen should be on the right, such as the city screen. That way you can click-click-click the cities and see if you are doing everything you want in the context of the world map. Much quicker. It has to be a setting, of course, because people play on laptops, but this UI improvement is just so huge that it's worth doing.
