Been previewing the new look on dev and things look pretty good! Love the android-app-style story items and like the overall less-busy colour scheme. Will miss the blue selection bar that is now yellow, but that’s just personal preference. 
One bug for you:

In the header of the story pane, the feed title seems to be squished/overlapped with the control buttons.
Firefox v17.0.3 on Win7-64, all custom styles disabled.
