It should alternate to be editable path location on click, like nemo and even god forbid windows.
This has been requested multiple times, but unfortunately has always been rejected because some people think it would cause “unexpected” behaviour for some users.

I have the opinion that every shortcut (or at least the main ones) should be referenced in the UI somehow.
