Sign Customiser now gives you greater control over how products are published to your Shopify store. You can now choose whether new products should be created as “Active” (immediately visible in your store) or “Unlisted” (active but not visible in your store or search results).
You can find out more about the new Unlisted status in the Shopify help docs:
