research buildings

another idea:
it should be possible to destroy a building even when you're on a negative balance or at least to know the monthly maintenance cost of a building before building it (at least for the more expensive ones). i built a research building without knowing it'd cost me 500 000 per month and in 5-6 hours i was on negative money and i couldn't do anything about it. it costs 50 000 to shut it down but where to get 50 000 when you have -2 000 000? so i had to reset the account and i suffered a lot for that (i felt like i've been cheating the other players when i started the second time )

i know about the manual but it's so loooong
just kidding. it was an unexpected surprise for me to find out that a building maintenance costs that much and a little frustrating to not be able to shut it down like a factory or a farm.
next time perhaps i'll be more carefull
