Something like that may be implemented one day, but actually all this is relatively easy to extract from exported SVG - most of the map features are grouped there, so there is a group with trees, a group with lights etc.
Would it be possible to add a `tiny` population density option? I really love those maps where it's mostly wilderness with just one or two houses, but it takes a while to find them by regenerating over and over.
The easiest way to generate a tiny village is to choose "Low" population density and "Tiny" map size. There probably won't be much wilderness (because the map will be tiny), but you'll get the right number of houses.
