Media breaks

There are currently only 2 media break options. Mobile and desktop. When you design a page to be viewed on desktop, it is typically designed to the match the screen you are using when designing it. When you then view the live page on a much larger or smaller screen, the elements will flex to fit the content, but not always in an appealing way. Currently, the only way to adjust this is with CSS and media querries. It would be great to have more options for different screensizes that we can use to ensure content looks good and be able to do it in more user friendly manner. A dropdown to select a screen size then edit that content for that size for instance would be amazing.
