Please, please allow styling of #respond h3. I know it's an iframe, but this is a royal pain as the #respond h3 stands out and does't fit in with my page CSS. Grr. A solution to this would be MOST fabulous!
I don't know if it would work, but what about just disabling the CSS in the options? Better yet, just disabling the font-style related CSS. Would it then inherit the CSS? If not, I don't know what the solution could be.
Otherwise, I love the plugin.
