Myself and my dev team is really struggling with this new interface. Its a bit confusing and most of all its really compact and hard to navigate. If you look at the screenshot you can see how much real estate and space could be used to make it easier to navigate through the settings. D0 we have a bad setting or is this what we to learn to live with. 🙁 https://www.awesomescreenshot.com/image/58166766?key=e4cb4b53d817f31cd3ee661c68b81c0f
Just like the Block editor, the new UI of the builder moves all the settings to the left side. The main area will show the field appearance, so the user can see how it is displayed on the post editing page.
