I'm building to have about 1,000 different domains in my multisite network. Initially I've been working with assigning a unique child theme to each domain. This allows me to change the background image and some CSS. It's a lot of work, though when you need so many child themes. Can you please explain if this plugin might be more efficient as I scale to 1,000 or more?
My main difference among all child themes is simply changing the background images. My second difference is I use about 12 different color combinations which are adjusted in CSS. If I could setup 12 basic templates, and then just change the background image for my 1,000 domains using this plugin, without the need for child themes, that would be awesome!
