It does way more normalizing than just the name of the function. It works around a number of bugs when the element is in an iframe, and it has a fallback if you're using it for video (which was the main reason I wrote it).
Hi Brad, I don't mean to discourage your work. This just fills like mostly a polyfill. Bug fixes should be included in polyfills. Nothing wrong with that, that's a valuable thing. But I don't want to learn a new API unless it provides a new type of abstraction over the Fullscreen API and this one doesn't seem to do that.
I suggest updating your "why should I use it" section then. I also saw a trivial polyfill and stopped reading.
I also like the idea of an option to fall back to making the element fill the page if the browser doesn't support the fullscreen API. You could even breifly display the hotkey to put the browser window in fullscreen if it supports it.
