I use this for setting up my client's sites on my Multisite. It would really be helpful if underneath each of the "Backend Settings" fields, there was an checkbox to "use same file as Frontend". So it's not loading 2 different files one on the front and one on the back. I've tried just uploading the frontend and pasting the URL's into the backend, but it just removes the URL's on save.
That feature would really make this "All-in-One"!
