That’s seems to me to be the lazy way out. (Also something Apple would probably never ever do. I can’t think of any setting in any Apple application that radically changes the UI. There are modes, like Aperture’s fullscreen mode but no settings. Their iOS apps have even less settings, if you strip away all the configuration there are probably a few dozen real settings in their Settings app.)
I love how the common user suggestion to "just make it a setting" is immediately downvoted. Hacker News FTW.
I can't tell if that's sarcasm or not. I hope it it is. I thought downvoting was reserved for the most egregious of comments. For me, that one by mikeryan doesn't count.
