everyone has been talking of elevators in v13. That would mean that onvehicletouch could be available.(if that change happens)
Who needs elevators? If your good with events you can make realistic looking elevators that are exactly like Trader's without and special mods.
Also, I just thought that maybe the whole purpose of this thread was to show off new stuff from v13, and I don't mean just the inverted arches. At some point in Trader's story there is a magic wand.
Maybe Badspot has been tinkering around with the wand tool a bit? o:
