I'd like for there to be an option to disable power/control during race set up and start, unless I do something that needs power, like calibration. When trying to get a race going, kids are always pulling the trigger and the cars only lose power when I initiate the start countdown itself. They can't keep from pulling the trigger while I'm gridding the cars and doing other race setup tasks, so I'm always have to yell at them (to be heard over the cacophony of kids talking loudly/yelling at each other) to keep their fingers off the trigger. Even adults have a hard time with this. RCS64 has a great option to enable/disable power while in menus, so the cars are pretty much dead unless there's an active practice or race. I'd LOVE something like that. If it's already there, I can't find it.
