UI elements can be difficult to select in the design layout, and so I find myself using the Navigator panel all the time in order to select the element I want. But then I have to constantly go back and forth between the Navigator panel and the other three panels for Styling, Settings, etc.. And it's quite a tiring dance.
I have plenty of screen real estate and could easily have two panels open at the same time right next to each other. Which would enable much quicker element selection and editing.
