Extend the sidebar editor to full width on small screens

[st3iny]

Is your feature request related to a problem? Please describe.

On small screens the sidebar editor can take more than 50% of the available width. The grid is squished to the point were it becomes unreadable.

Describe the solution you'd like

I propose to extend the sidebar editor to the whole width. Like we do it in Mail when viewing threads.

Describe alternatives you've considered

Shouldn't extending the sidebar to the full width on mobile rather be a default for the vue component?
