Nice and you could probably make it save in under 512 bytes. Just persist everything to localStorage like the tiny spreadsheet http://jsfiddle.net/ondras/hYfN3/

Or save everything on the URL so it can be bookmarked too.

You know, thare's already a save function: you can write stuff in the cross-browser editor and save it on your desktop as a standalone HTML page (Ctrl-S / File > "Save as...")

I recommend you to use Firefox: it will keep the code in the textareas. Chrome will only save the iframe's content.

;)

Yes, saving to URL would make this also shareable, so it would become real 'self contained Codepen' :]

I've made something in this manner recently: http://tinyurl.com/selfcontained-editable-datauri

I like this idea!

Feel free to fork miniCodeEditor and add this kind of features :)
