Hi, Oleg,
Can I suggest two new buttons in the layout menu.
1.Specify number of gates (which also decides number of roads leading from city). I know that this can be done manually, but it is much less convenient.
2. Specify number for deciding size of city (& number of buildings) - eg much smaller than small (say 5) or much larger than Large (say 100). Perhaps add a Custom Size under the Large button, which makes you choose the number for either size, or perhaps number of buildings. I have successfully downloaded a city of size 250, and converted it into a map (to give me a city that realistically can have a population of 1,000,000.
This programme is possibly even more powerful than you know.
My city is the capital of the largest nation in my fantasy world - a sort of Constantinople. It has 235252 buildings - pretty impressive.
