With the advent of hotels, mega farms, and people constantly looking for jobs, I think build permissions should have a Y coordinate restriction. Think about it this way...You build a hotel and a person rents a floor. They could have build permissions from Y:100 to Y:104 so they could build whatever they wanted and people who own the hotel wont have to worry about them breaking or stealing anything from any other floor.Or...Say someone wants a job and you own a mega farm. You would gladly pay for someone to farm for you but you're afraid they will break or steal some of your other items. Simply restrict them to Y:64 and they can only access the first level. Or if you own a massive sugar cane or cactus farm, restrict them to Y:65 to Y:66 and they can only take the top two levels off and not hurt anything else.Thoughts?
