FormBuilder UX general improvements
Overview
This feature request stems from the monthly FormBuilder meeting and some product research of other form building tools, such as Webform (Drupal) and WPForms (WordPress).
Current behaviour
There are several aspects of the FormBuilder UI that are not as user friendly as they could be. Taking on the UI overall is quite a big project, but it can be parsed into smaller portions that can be easier to tackle, such as making the listing of Entities span the width of the screen so that the user has more real estate to see what they've added to the form.
Proposed behaviour
I've created a wireframe with some ideas the meld an improved design of FormBuilder's current layout with some of the better features of WebForm and WPForms.
