I'm back! :pilotfly:
Well, Save/Load are there, but possibly for completion-ism, similar to switches being present but non-functional in other moduldes. We shall see, Saving and loading could cause issues or end up a pain for users should the NS430 become available for other aircraft.
I could not personally answer this question, I'm not that guy, I'm a bug reportin' guy :)
I'll maybe make it a suggestion or something if I can, could be handy, not something for me personally but I can see why you'd want it as an option.
As for your knob scroll problem, I cannot trigger this problem in any build I have sorry.
Are you using the latest openbeta?
And, if so, maybe try running a repair.:joystick:
