As someone who likes to make various types of maps with ports, I have a hard time creating truly detailed ports as there are no warehouses, wharfs, drydocks, shipyards, fisheries, ships that are under construction, pieces of ships like sails, or other details needed to make a truly stunning port.
This suggestion would hopefully go for all or most of the map types as all of them have details that are missing to make a brilliant port.
Any feedback is welcomed.
