@lispi314 right, and still worth aiming for such a thing. Hard but vital work.
Good documentation will always be a good thing, and ought to be included everywhere possible. And requiring users to use documentation should be done only when absolutely unavoidable or explicitly wanted.
A nuclear power plant likely should have controls an untrained person can’t access and use, for instance.
@davidaugust I can agree, particularly for emergency or essential controls, it should also be careful not to remove all the other controls that a more trained user might want to use however.
