I have REALLY enjoyed working with your theme. The first starter theme I built was using the Genesis Sample theme, but Utility Pro has become my new base.
I’m now completely sold on mobile-first design and development, and I’m really glad you took this approach. I also really appreciate the way you have kept the functions.php clean, including other files where appropriate. It has been a great example for me to follow in my own practices, and I’m now doing the same to include editor styles and custom widgets I frequently use.
Other things you have included that have just saved me tons of time – code to enforce recommended and required plugins, a fantastic mobile menu, and how could I not mention how easy you have made it to get a massive head start on creating a site that is more accessible… Really appreciate the great work!
