It sounds like a lot of work when you write it out, but in reality it is tons faster than hunting and pecking for the right spot with the eye droppers.

I definitely agree with not putting a lot of processing into proofs. I recently decided I wouldn't do any leash removals or other work beyond very basic color and exposure on any proof until it becomes a selected image. It went against my original thoughts about never showing anything but a completed work at first, but when you're posting 300+ proofs from an event it sure saves a lot of work.
