so, recently I made a few cities with your generator, and I was wondering, is there a chance to make a tool that whode combine them to make a map of sort 
Or, is there a chance to make a button for zooming so when I export  the .png of the picture they will be in the same hight and I will have an easier time putting them together 

keep up the good work 

I don't know how you combine them (do you make a large city of several smaller ones, create a region map with several separate cities or something else?), but it's seems to me that such things are easier to do with svg export - no quality loss and also all svg's come in the same scale.
