Using Windows 8 Release Preview and seeing this is still not implemented is painful. I don't know what to say. Words are useless. If you say this is too much work, which definitely isn't: You can't even change a folder's damn icon without leaving Libraries. Or if you don't mind an example outside Libraries, you can't even "Open With" multiple files. You really leave me without word. When it's about marketing, you can add something brand new & huge, like the Metro. But you can't even fix simple lackings who knows how many years old.
I think this won't change for full version too but still i have to ask out of my incurable curiosity: Is there any chance to see it fixed on the full version?
