Feature Request: Output a full-size screenshot of the site to the right of the generated one.

As the title says, it'd be good to have the reference to the right, that's the next thing I want to do unless I want to alt-tab or use a separate screen.

This could be an option or the default, I think either way works because of the nature of the plugin. It's not meant to be 1:1 because that's too complicated (TM), so until it somehow is, perhaps the reference is useful.

I'd like this a lot!

Thoughts?
