WetGeek Probably would have had a feeling that something was different,
Unfortunately, that infatuation didn't last long for me. Lots of icons that weren't obvious to me at first turned into little empty white rectangles. Hovering the mouse over them displayed their tool-tips, so I was still able to find out what they stood for, but not by sight alone.
I may do some more experimentation later on, but for now Breeze Extended seems to be comfortably complete. I think that will be my fall-back while I experiment with others. Pleasant enough looking, even if it doesn't make my heart beat faster.
