We know that the editor currently has an expand button:  However this edit mode is (as I believe it to) rarely used. This so, because it is a bad writing experience. You loose all your context for the sake of writing space. I for one love to be able to scroll up and down, and have my writing experience stay consistent! ### Proposal I propose that we give this option for screens wider than `>1280px`, while the old "fully expanded" editor experience stays where it is for viewports smaller than that `<1280px`. Instead of a full screen experience let's split up the view, possibly hide the sidebar (at even wider screens, it can be shown as well `>1440px`), and show the editor next to the existing discussion thread:  I propose to have this instead of the current full screen writing mode. #### Implementation I think this could be done quite easily, by manipulating the css with js. cc: @awhildy @JobV @markpundsack @tauriedavis
