Yeah. In the future.

I am NOW working with clients on their site.
I create NOW new sites for them.
And NOW i do not want my clients change the full site design.

The WP Updates are a running experiment with every update and new features. Opens more and more design features for the client - i and the client do not want.

As a long WP developer - currently i am making some tutorials in laravel and sympfony - to get the controll back. my client only wants to change the content, not the design.
