This is honestly the best and most complete visual style since Lion Inspirat. Really nice colour scheme, flat and minimal. I think the windows drop shadow needs a bit of a touch up at the corners though and like others have said maybe the min/max buttons could be changed. Shame about the lack of navigation and search but I think that would make the top window bar bigger and spoil the look no? Great job and I look forward to a final version maybe with differents colour scemes (light windows/taskbar, blue/red highlights).
