Single button to fold all side panels

I am working a lot on my laptop, meaning I am collapsing and opening the side panels (app structure on the right and files on the left) to get a good size coding view.

Would it be an idea to add a “fold all” button (and short key) right next to the “split” button (or a double click) so that the code/design view becomes full width? This would save some time navigating and clicking two buttons for the separate panels on the side.
