The "Maximize the workspace" is very useful (especially in the group space) and it'd be convenient to encourage its use. It's difficult that people will see it in the "More" menu, or even relate it to the document they are editing. It'd be better to have a "Maximize" button typical from any window in any operating system. Maybe right now it can be next to the (i) (information button) that we see when opening a document.
