Concerning the Mutiny layout, I wonder, will it ever look like Unity, I mean, technically, is it possible?
I've been using MATE for almost a year now and there are still many little glitches that make it far from the smooth experience I had with Unity. Some of them pretty big. And the Mutiny layout depends on the dock applet. And the only dev of that applet has noted that it won't be developed further. So there is still plenty of work to do.
But for me it's still better than suffering through the choices that Gnome has made of the past years.
