I like it when Weston Ruter puts on his lab coat and goes to town with the customizer. In this case and as I've seen mentioned already, editing should be done inline and not with boxes popping up around the content. With the Front-end Editor using the Customizer as a framework, I wonder if the interface will look similar to this experiment? I hope not.

Ultimately, I'm interested to see how the Front-end Editor comes into play when previewing a post or writing a draft post. Will we be able to use it to write a post or will the editor be refrained from use until after a post/page is published?

What will Weston think of next to use the Customizer for? Maybe order me a pizza :)
