This is a great Thread, a great Idea. Thank you so much for this.
I started with Big Box a few years ago. I liked some of the Themes but there was always something i wanted to have changed.
Therefore i reverse engineered and learned by myself from scratch what each program codes do if you change this and change that.
It took me weeks of hard work but in the end i made it happen to have my theme personalized how i wanted it.
But i always thought why there is not a Template where unexperienced Users could create their Themes how they want to.
