I don't know if this can be done with modtools, but what i think this game needs is a simple city manager, like found in other 4x games, like the endless games.

For example, you can set a city on Energy mode and it will only make Energy. It would set the city focus to energy and build buildings that would increase it's energy gain as soon as it was available.

You could set this in a city and then forget about it and it will just make you lots of energy without bothering you for inputs now and then.

And this should be possible for all major resources.

Food
Energy
Production
Science

It would sure be nice and remove a lot of the lategame annoyance of managing lots of cities which pop up with input every turn. Sure you can set a city to produce energy but you can only queue it up for 6 turns.

Maybe the devs will actually put a thing like this in themselves in the future, i feel like it should be standard in 4X games like these.
