Right now I have a site that uses the flexible layout field and over time we've added various new elements the user can use to author their page. The result is this big drop down list and it's just not user friendly any more. A screenshot is attached. If instead of a list a more horizontal popup could appear with icons and labels (i would have to define the icons naturally) this would transform the experience into something far more visual and user friendly and quick to locate the item needed.
