One Shopify tab in a repository's settings
Theme previews, theme documentation and the guide's settings now sit on one Shopify tab. The store, its credential, the storefront password and the preview theme limit are set once at the top and used by everything below, previews on or off.
Under the store, sub-tabs hold Previews, Theme docs and the guide's address, password and look. The store can now be chosen with previews off, for a repository that wants only theme documentation or the merchant content check.
