It would be really helpful to have the ability to set the prototype device by frame and not by page.
So that when you’re designing a component or page and you want to preview or present prototypes to a client you can have both desktop and mobile on one page, not having to create a new page just for mobile. Then the page name could be ‘Hero banner’ or ‘Home page’ and you can have both desktop and mobile design on the same page. Just a neater workflow and neater file management.
