* Adds a priority call mode that allows heads and first responders to cancel all calls and summon the lift to their floor immediately.
* Adds a firefighting mode that turns the lift over to manual control, doors only open when manually opened, all call buttons ignored. For use during fires.
If one floor is 'taller' than the others, or otherwise takes longer to traverse, you can set delay_time on the area to have it wait a different time there. Or, wait even less time, though less than 1 second isn't possible since the controller only fires every second.
