[tiny new feature proposal] by default space between "close window" and "restore/maximize"

Hi everyone. This is a proposal for a tiny usability improvement, in my biased opinion. A bit of space between "close window" (the X) and "restore/maximize" (the boxy thing) up right, on the window border. If you remember, kubuntu did this once. You can already do this your self, i'm just proposing to make it the default config. If the devs feel, enough people approve of it on the mailing list, they will do it. So make sure to share your opinion.
