When it comes to locking the mass or radius there is a problem. When I want to lock both the mass and radius, I can only lock one of them at a time. This problem really bothers me because when I finish editing the parameters of a value, I want to lock it. I want to be able to lock all the values, mass, radius, temperature and luminosity (for stars).
All celestial objects which involves planets, gas giants and stars must have the ability to have their values locked and unlocked when users want to lock or unlock them. When saving celestial bodies, their locked values must be saved with all the other properties of the object.
Please make it possible for Universe Sandbox 2, to make it possible to lock more than one parameter value on the properties of celestial objects.
