You're absolutely right, we are working on providing some examples soon enough. We have two clients using it in production but their websites are behind a login wall, so I'd have to share screenshots.
What kinds of website would you be curious to see if we can handle?
I don't have a prefernce. Screenshots would be nice.
But showing is better than telling, so why not also use your own tool to build a basic website that does something, even if its like a fake store or service as example?
