Upgrade the Responsive Previews

I feel we could use some more ‘mobile’ views to be able to really see how a site would look if say on iphone 7, ipad portrait, landscape, and larger tablets like 992px wide, iPad pro. It’s sooooo difficult to get a sense of what my site actually looks like, and constantly having to publish it and check how it looks using the Chrome inspector other tools because the BB preview is SO LIMITING.
