As our Designs & Layouts overview discusses, a ProPhoto design consists of a group of layouts. Whenever you create new layouts in the Visual Builder, and make changes to them, all of the layouts are being saved to the design currently being customized. However, ProPhoto is very flexible in that it allows you to create new designs and switch between previously created designs at any time. This allows you to change the entire look and layout of your site very easily.
To get started, head to the “ProPhoto > Manage Designs” area in your WordPress admin.
The manage designs area has quite a few options for managing the customizing design and the live design and adding new designs.
