Agree'd. We've got it on our wish list and are looking at ways to either auto zoom and/or auto snap, to say a Approach Plate (if loaded) or others. We just have to be very careful and give the pilot control and set it. We tend to lean away from auto features as the pilot needs to be in control, but it can make sense in some cases.
ps- You're not wearing me out... We thrive on this information.
