When it comes to building the best website builder on the planet, it’s important that we focus on not only what the builder can do, but also on how those things get done. The Divi Builder interface is a place where hundreds of thousands of designers spend their days. Each click, each move of the mouse, every single interaction is important to us and we want to create an interface that is a joy to use for everyone.
Today we are introducing new interface customization options along with two brand new interaction modes for the Visual Builder. These settings put the controls in your hands, allowing you to tailor to perfect building experience for your unique preferences.
