One more for the wishlist: a switch that would make manning certain habitats optional (that is no warning message). Why? Sometimes ships are deliberately understaffed, with certain crew using multiple facilities part time. (
Example: a science officer might have a control room station, an office, a lab and periodically oversees a rec room establishment with the ship's doctor, who has her own sickbay, lab and office.) In addition, in commercial vessels (and buildings) some facilities are intended to be rented out to passengers on a temporary basis.
