An area of the Frontastic Editor where frontend managers edit global pages.
In Master, you can create templates ( Blueprints, Tastic kits) that can be reused across your pages and Master pages that are used across your site, for example, search, checkout, my account, error pages, category pages, Product Details Pages, and so on.
Below is an example of what you will see when you first open Master:
"In Master, I've added a new Blueprint for our pages as well as creating a Tastic kit for the header. I've also created the layout for our new checkout!"
For more info, see the Using Master article.
