Don't know if this has already been suggested but, I propose a prestige option which would allow players to change the location of their buildings on the city screen.
This would be purely a cosmetic change, which shouldn't have any impact on gameplay (unless the building position in a city actually affects anything).
I doubt most people care where their buildings are located, but there ought to be some that like to place them in a given way. With the new buildings, some may be unsatisfied with their building placement, but don't want to waste the time on demolishing buildings just to change their city layout.
This option could, for lets say 3 prestige, allow a player to swap the contents of two plots. Obviously there is no reason for a player to swap the location of resource buildings, nor should it be possible to change the location of the Common Ground, Paddock or the Castle (Wall).
