Will a fullscreen option native to the Mac OS X be developed?

edit

I love using the fullscreen option for many programs on the Mac OS X, so that I can swipe back and forth between them. Are you considering developing a fullscreen option native to the Mac OS X? It's the green button on windows at the top left corner that you can press to get a full screen in many programs native to the Mac and ones that are developed by other developers (e.g. Google for Chrome; Opera; etc.)

Pretty Please!

Thanks!
