Async requests
To improve user experience Echo features has been created. This allows to test asynchronous requests, add javascript files, create workers - all from one fiddle, so it is more transparent for the user reading the code.
Asynchronous requests are split to HTML, JSON, JSONP and XML. Gist and github responses are similar to the echo feature and go nicely in pair with storing fiddles in gist and github.
