I stumbled on your generator, and its superb! It will come very handy for any RPG.
But may I suppose one feature - city population count. It is sometimes hard to track how big generated city is, but knowing roughly how much inhabinants it have, based on number of cells of certain type will come in handy.
To calculate city population I would need to make an assumption about population density which may vary widely. Instead you can calculate it yourself by multiplying the number of buildings (press and hold the SPACE key to get it displayed at the top left corner of the map) by a population density value suitable for your setting.
