This seems like the opposite of options. (Not that it doesn't seem like a pretty nice tool -- if for nothing else than jsfiddle on steroids.)
Tools such as JsFiddle, CodePen, etc. are extremely limited by design. They are intended to simply demo and showcase HTML, Javascript and CSS. Codio is a fully-fledged IDE and code editor, and does a lot more. Take a look at our homepage and you'll why.
So while we can do what JsFiddle and co. can, and would be delighted if you used it for that purpose, our main goal is to get you guys to use Codio as your IDE of choice.
