SHOPIFY THEME PREVIEW

In the context of making modifications and previewing your new theme on Shopify, it's important to note that Shopify only permits you to display the current pages. When you are within the theme editor and crafting templates, these templates are dedicated solely to that particular theme and only able to be visable in the theme editor of that theme to view and edit.
It's only when you publish your theme that you can visually experience the design when you assign the template. This is a standard operation that applies to all Shopify stores. It's a unique aspect of Shopify's design functionality that facilitates a smoother, more controlled approach to theme customization and implementation.
If you're on the brink of launching your online store or considering a fresh new look for it by introducing a new theme, you have the opportunity to gather valuable input from others by offering them a preview of your upcoming design. Creating a preview link for your theme in Shopify enables you to share it with others, even before it's officially published. This means you can collaborate and gather feedback without needing to make the theme live.
The beauty of a preview link lies in its ability to grant others access to explore your online store's new look, while ensuring that they cannot proceed to the checkout stage. Each preview link remains active for a duration of 48 hours, providing a window of time for others to review and provide feedback. Importantly, the creation of new preview links as needed does not interfere with the functionality of previously generated links.
At the heart of this process is the desire to refine and enhance your store's appearance, and sharing a preview link is a powerful tool in achieving this goal. By involving others in the preview stage, you can benefit from fresh perspectives and valuable insights to ensure that your new theme truly resonates with your audience.
It's important to note that you won't have visibility into templates that haven't been assigned unless the theme is live and subsequently linked to specific page templates.
