What's new in Dropbox - 5th Edition

Add tagging capabilities to files.  Then add a way to sort/view by tag.  Folders work in some areas but are cumbersome in the photo folder.  This seems like a no brainer but would love to here some technical/marketing/business related reasons why this isn't practical.  I see Dropbox attempting to grow outside of file storage with Paper and the new professional oriented services which is cool BUT Dropbox is used by the masses because it does one thing better than everyone else- effortlessly manages files across multiple platforms.  I want to support Dropbox and see them do awesome.  The direction they seem to be going doesn't appear to jive with the reasons I use the service.  Any thoughts?
