I installed it last night and was pleased to see that a little work had been done to make it more PCLinuxOS like in the taskbar setup, and wallpaper...so it was a little different than what I expected in regards to vanilla XFCE, but a 3 minute stab at picking a different theme turned up fruitless for picking a Phoenix theme (or any other theme really, I don't know XFCE very well).
So if it would be as simple as making a Phoenix theme package, that would be cool. Just another way for people to enjoy your Phoenix handy work and to consider full time XFCE desktop as an alternative without doing another install.
