If anyone from Shopify is reading this, being able to just visit a sample store would be great as a first step before having to go into a dev environment (which like many people I don't have on my phone where I'm first encountering the announcement)
I get that it's a dev tool. I still want to see an example end result before I invest time in learning the dev tool. I'm not alone in that. There's a reason why "Demo" links are common. They increase the odds people spend enough time with your product to get to the point of adopting it.
