Wannabe 9 or 10 or something

I've been working on different mockups of what I'd like for Windows 9, but since we now have a better view of what it would actually look like, I've made a new one.

On the menu : tabs ! no search box (a similar system as Ubuntu, you just type when the window is selected, or use ctrl+F if you prefer), only one option button (with "new folder", "copy", "paste", ... all that good stuff), but icons can be added between the adress box and the file button (just like in Firefox), new icons more "flat", borderless windows with good shadows, and a new overall friendly appearance.

I hope you like it. And as always, don't hesitate to share your thoughts on what's good or not, it's always appreciated
