i think a great idea for this game would be a ticker screen that you can pull out of the sidebar under your character portrait that gives you a rough estimate of what your city is producing and consuming on an hourly basis, assuming that the productivity continues at its present rate (ie no quarries / fields or wells dry up)
it would make tracking how much you can spare in the case of items like fir logs (when youve got coking plants and sawmills running in tandem) a lot easier, as well as generally give a player a better idea of what theyre capable of based on hourly resource rates.
