first thanks for all of your help, you supported me and my work for years now.
I'm about to renew my portfolio layout (using X-Pro).
I activated the under construction plugin.
Now I would like to make a complete new layout without deleting my old one and without making a copy of my WP installation.
I know I can easily do it for the header your showed me how.
But what about the full design? Like full layout instead of boxed, extra css I added and I don't want on the new layout etc?
There's a way I can start with a fresh new layout without deleting my actual one?
