Under Email Actions, you'll notice some new features. Upload an Image or File, and Grab Images from Web. You can also save the email itself as a new email template. All you have to do is give it a name and a destination.
When saving an email as a template, variable values will not carry over. Variables will continue to use the defaults specified in the underlying template. Available modules in the email will also not carry over unless they been inserted into the email body.
Grab Images from Web works just like it does in the Design Studio.
