I request that all 5 layout formats are enabled by default in the WP editor. When I'm working with the pages, I need to check every layout / screen width option, and it's such a waste of time. Right now, there are only 3 available by default without adding to EACH page view. Please consider these options:
1) Allow us to select which display widths / layouts we want in the master settings. This should be respected by the editor for every page and it should display these by default when entering the page editor.
OR
2) Enable all layouts by default in the editor.
For clarify, I'm referring to the icons at the top center of the page editor representing these real-world viewing platforms: Widescreen monitor, laptop, tablet, mobile landscape, mobile portrait.
