Layout View in Setup Mode

Would anyone else like for there to be an option for the selected layout to be displayed when it is selected in the Layouts list in Setup Mode? I feel like this would be a great addition to the preferences. I guess it would be confusing if one was selecting multiple Layouts for some operations, but I feel like it would make things much easier when working with individual layouts.

It takes time to render each Layout. This would slow me down to much to be useful, IMHO.
