The whole thing of calling controls "chrome" is basically a metaphor gone horribly awry. The term was coined in the 1990s because (at least on Windows) the "content" usually had a white background, and the controls usually had a gray background. But of course the use of the word "chrome" inevitably implies that this stuff (the controls) are like the chrome on a car: nonfunctional, inessential visual frippery. And so UI chrome must be bad, and something to eliminate. But of course this is nutty: The UI controls are what you use to manipulate the content! It's like calling the steering wheel and the pedals in a car "chrome" and deciding you need to deemphasize them so that the driver can 'focus on the road' or something. The controls are important! They are how you drive the car!
