Build in confidence and prediction bounds in the Surface and Contour profilers and allow the user to toggle them off & on and to set the alpha values in a pane off to the side. You can use a different surface transparency on the surface profiler so you can still see the underlying shape of the prediction curve.
Would be great if the confidence and prediction intervals could be integrated into the projected contour plot underneath the surface profiler and connected to the Response Grid Slider. This is super useful in explaining how a response requirement i.e. the Grid Slider intersects the prediction surface. Would be super useful in explaining to project management when "it depends" whether or not a requirement is met.
