Yes, but it doesn't save them.

You hit refresh and those changes are gone.

I see the value of this for alot of one-person development shops or front-end devs that do a lot of client design work.

Your client calls you, "Hey, this thingy here isn't lining up right"

"click. click. publish"

"refresh the page"

"ohhh....how did you do that?" (Client amazed)
