> the misguided idea that somehow one particular piece of functionality is a vastly more important value proposition to the user than all the other features But isn't that mostly true? Doesn't have most software you use have a few core features, some you sometimes use and some you never use? A good UX revamp orders correctly these to appeal to most people (but of course too many are too aggressive about removing things).
