Didn't get the formatting right on the post; first time submitting something on HN. I'll add a tag next time. I disagree with your point about how you're _always_ going to need to view the HTML/CSS. Sure, there's always a point at which it will become necessary, but when is it completely unnecessary? Do you really need to see the HTML for every button you put on the page? What about a header? A tabset?
