It would be a great feature to have the URL's visible and clickable in the report. Right now you only have test and reference, but it's not always clear what test and reference means, especially if you use Backstop on a lot of environments (like, test, staging and production).

The same goes for viewport, but that's allready in the name, so it's less of an issue right now.

How do you make the url and reference url show up on the html report?
I see what fields out should be in config.js.
