There doesn't appear to be a way to see what (javascript) code to add to a site, after the initial setup, unless it's well hidden.

So if you need to rebuild a site, or, in my case, want to remove all the Chartbeat code, there's no way to see what code to look for (I can deduce but finding the header stuff was harder as there's no mention of Chartbeat in it).

In other words, really needs a way to edit/show a site settings, rather than just add. One way round this would be to add a new site, just to see what the others might look like.
