I think it would be awesome if we could use the Upfront Builder to style and customize the WordPress Admin panel available to non-admin users. Allowing them to set different layouts and styles to different roles would make it great for highly customized websites.
I'm sure every user would love to be able to fully customize the back-end experience of their website's users, if they have user membership area, of course.
I hope you take this into consideration.
