Perch 'theme' options
I've been asked to create a theme or template for a basic Perch website that can be sold much like a Wordpress theme. The client would install and load the files and add content. I'm confident this won't be an issue as I already use a base website 'theme' for my current Perch projects.
My question is regarding allowing design configuration options such as setting layout colours and fonts. This won't need to be overly complicated but I'm wondering how others would do this and what they'd recommend? I could setup a region in the head with an internal stylesheet but I don't really want to do this. Any ideas?
