Mobile view to help with page building

Could the admin have the option to "view on a mobile screen", while building pages on a large screen? This would make it easier in situations where admin knows that participants are primarily participating on their mobile devices.

For example this is the way it's done in Microsoft Forms preview-window. Helps quite a lot to adjust page properties especially if you are planning to facilitate mainly mobiole device using audience. Example picture taken from one of my Forms questionnaires.
