One thought regarding the pedestal cut out switches.
I find it lacking in functionality that you can not disconnect all automatic trim like STS, Mach trim and MCAS and still continue to have manual electric trim available. The two switches should have been configured so that one cut only the automatic trim functions and the other cut all electric trim.
That would in my opinion have given more alternatives for the crew as I am sure any crew would very much like to have manual electric trim available after any run away automatic trim had been cut out.
If I was FAA this would be (the) one physical item/functionality to change before lifting the grounding of the Max.
