Hi there, very excited to start working within the new Online Store Design Experience. We currently manage a handful of Shopify stores and are anxious to prepare for the upcoming themes overhaul. While we've been able to start taking a look at the code changes, the documentation is still very thin and with no way to access to the new Theme Customizer UI it is difficult to fully grasp all of the changes.
Is there a timeline yet for a preview of the new Theme Customizer UI? Or a timeline for the new Online Store Design Experience to be publicly launched?
Glad to hear you’re excited to get started with the new online store design experience! Currently you can test out the new theme file structure and content model with a developer preview store, however, the Theme Customizer UI is still in development.
We will be announcing a timeline for the partner release in the coming months, which will ensure that developers have ample time to prepare in advance of the full merchant release. We are also frequently updating the Section themes REST API changelog, so I’d recommend keeping an eye on this forum post.
Hope this helps,
Shopify | Developer Advocate
