Just made for fun. What OSX could be in a near future… or not. ;-)
It's a rebound of the Windows redesign made by a Dribbble member (but I don't remember who).
I tried to simplify the current UI and UX of the system.
I'm not sure about the hollow icons over the file (here the 'Image004') because QuickView, Tags and Share are also available in the right-click menu.
