It would be nice to have some 7-days chart of changes of stocks, I know there is your total balance for 12 h in economy window, but it includes also consumption of buildings which does not produce resources due to reaching maximal limit so the overall number is not really helpfull.
Also an option to pay quest resources anytime during quest not just after the "production part" is finished (for example any quest of produce/pay horses is literally impossible without sacrificing some cavalery on purpose)
