Is there a way to edit the code as if it were just text? ie. not have to double click the values?

Yes. You can edit CSS in Resources panel (http://youtu.be/N8SS-rUEZPg?hd=1&t=7m18s) and JS in both Resources and Scripts panels. It doesn't have any code completion yet. Also, you have to double click to enter edit mode (I don't know why https://bugs.webkit.org/show_bug.cgi?id=71645).
