If you are working on your email templates and need to sort them in to a different order, this can be done by clicking on the Sort Templates button. A side panel will open to the right side where you can click on the name of the template and drag and drop it in to the location you want.

When you are done sorting the templates, click on Close at the top of the side panel to go back to the email template options. They will appear in the order you changed them to. This can be very helpful if you are working with a set of email templates on a regular basis.
