Improved inline expanded Editor
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.
