I saw your comment after submitting mine. I'm sure using the customizer as the framework can prove really powerful, and better for future development.

But my comment was more about the user experience, and as it is now, I don't really feel like it's doing a good job at it. But, since you're saying it's a prototype, I'm really looking forward to see what'll come up next !

I really think post editing (as a front-end editing thing) should be as much as possible an inline experience : editing the post title, content, etc directly where it's at, and not in some form fields poping up around it.
