Metropolis Sprawl
A little mod to deal with my own personal gripe. It changes the province capital requirement for upgrading cities to metropolises so you only need the city be a province capital only if it is not adjacent to an already existing metropolis. This way one does not need to do pp-intensive capital switcheroo maneuvers to truly turn their whole home province into a sprawling megacity. At least that is my intended use for the mod :D. Should work for AI too though I have not tested it.
