Collapse the left pane

It may already be on the roadmap, but I think the ability to collapse the left pane would improve the UX of the editor.

I’m assuming the Gmail menu works.

Thanks.

Yes, we can get more of available space to edit apps, like column settting etc, by sqeezing the width of control pane.
