When switching between branches, I always have existing files opened and want to quickly close them all but not the project.
I often just use the keyboard shortcut Command W to quickly do that because "Close All Files" does not have a shortcut. But my overzealous finger will obviously end up closing the Project itself.
So either provide a keyboard shortcut for the former or a warning dialog for the latter.
