1. It'd be useful to have the units that are assigned to each unit type/role come up in a list somewhere for each unit type, to get an idea of what type of unit falls under that category.
2. It's been mentioned before about being able to select the country you want a city to be assigned to, or to be able to add a pre-existing city to a country... if separation of the manipulation of countries and cities was possible, hopefully it would be possible to delete a country without deleting its cities?
3. I'm aware there is the option of making units country specific, which was in the engine to begin with, and that when the scenarios join the custom maps you will be able to choose the option that the unique units there can only be made by that same nation... but would it be possible to have a scenario option to have certain units available to be made by one scenario side, regardless of where they start?
