There used to be a link in the CCS editor that displayed the CCS style sheet for the template (I'm using Sight and Academia). That link seems to have disappeared with the recent new design.
Others are also having the same problem and it hasn't been resolved. http://en.forums.wordpress.com/topic/view-your-css-stylesheet-missing?replies=6
I've managed to figure out that you can see the stylesheets by using the URL below and inserting the name of your template but it'd be great to have the link to these sheets on the CCS editor page as it's an extremely useful reference.
