Idea: Expanding the Backend Designer

With backend designer – super idea and well done. if this could be extended to: hide items based on user roles, re arrange sidebar items to move them into different top and submenu – (which would clean up backend) – this would literally remove the need for any other plugins like uipress, wpadminify, whitelabel cms. its just 2 little things needed i think!

What do you think about this idea?
