Thanks, Von! Now that I think about it, you're right that it would have to be programmed differently. Also, I've realized that if they do give us forward and backward controls on the flying spiral, it will still be helpful to have a "reverse" option, or a way to flip the flying spiral the way you can flip the direction of the wheels. This would affect which direction is the default when both forward and backward buttons are pressed, which is important for machines that use two flying spirals to move as well as steer.
Again, thanks for telling the developers about this idea, Von!
