Guide feature request: option to hide the right-hand menu when writing/editing articles

Hi!

When writing or editing articles on Guide, a lot of space is wasted by the right-hand side menu.

The only option from this menu that provides value to the user throughout the documentation process is the Save button. All other options are mostly used at the beginning and/or the end.

As a result, Guide users without a two- or three-screen setup need to either:

• Get accustomed to the cramped workspace.
• Work without a side-by-side setup, which in itself is a waste of space. It also slows them down, if there's a need to check information in one application while writing/editing on Guide.

By moving the Save button to a different part of the page and providing the user with the option to hide the right-hand side menu, you'd make Guide a lot better and more pleasant to work with.
