Showing empty folders as a different faded grey or different icon would be a time saver. This idea is basic, however many people have a pre-defined folder structure.
Even windows can't seem to answer this one, and it too has never had a great empty folder icon.
Organization and structure are a good but getting lost in empty folders is a waste of time that could easily be avoided if this type of visual representation was implemented.
