Nice.
I'd welcome the return of any decent amount of colour customisation.
Not for any particular aesthetic reason Larry, but because my eyesight isn't so great with low contrast views. So the almost homogenous sea of various shades of grey that is Sonar X* is a serious annoyance to me. I've changed as many of the options in Sonar as is possible to help, but even so, I have to run my 24" HD monitor at 1600x900 instead of the recommended 1920x1080.
