Orbitersound has a function that will disengage autopilot for any time compression above 10X, and it works with any ship. The idea of boosting that to 100x under certain performance criteria is interesting, although I am not sure if frame-rate is the best trigger. It might be. Any thoughts?
Frankly, though.. this is all beside the point of my original request. It's not the autopilot that causes me headaches with time compression. It's my own silly self when I try to perform a very slight RCS manuever at 10x time compression (by accident) and I end up throwing the ship into a spin. It's just a nuisance.. nothing more. I will just download the Orbiter-Undo addon which should fix me up. I was just thinking more preventatively that I would be less likely to make the mistake if a visual indicator was right where I would be looking when it's time to make a maneuver.
In the end, I don't really get why the idea was so quickly shot-down. It's not like it would be forced on everyone: just available to those who chose to download it. If I ever delve into making utility addons, I'll just make it for myself .
