many thanks for this lifesaver

I was utterly dismayed to see the old Jetpack CSS editor disappear in favor of a little customizer box in WP 4.7. Thank you so much for restoring the legacy editor where we can actually see what we’re working with, and where our designer can work with CSS without having to upload style.css every time they make a change. It’s a vital part of our workflow and the little box in the customizer is completely inadequate.
