Inspecting DOM as HTML w/ Plunker

Is there a way to see the DOM as HTML in the Plunker sandbox? When we are changing the DOM it can be nice to see what the new document looks like, in HTML form. The only way I've managed to do this so far is to put the code in an HTML file, load it in the browser (Chrome), then look at the Elements in DevTools. That's not all that hard, but is there a simpler way?

Does this make sense?

Start by reviewing the Plunker sandbox workflow and the current tutorial or issue context for DOM inspection. Determine whether this request needs documentation, a sandbox capability, or only an explanation of using Chrome DevTools; the work is done when the supported way to view the changed DOM as HTML is clearly established.
