Tried it out for an hour or so. Must say, itīs fast, but not quite production ready IMO.
These are the things I noticed (was annoyed about :-) ):
Media Manager, whenever you push something, it doesnīt automatically open it, so I have to press the "right" button. The fewer button presses the better in a car. I know double-click works, but thatīs difficult when driving.
Where is the one-click option in the setup?
When browsing down through a list, there is
no fast way to skip a LOONG way down, except pressing "down" a 100 times. I have a LOT of artist and albums.... it takes for ever, and is difficult in the car.
The "direct-load" feature is gone. I think CF is way to playlist oriented, a lot of us guys donīt sit around making playlists for all kinds of driving, some times I change my mind and decide to hear something else. I have to clear the queue, find my album (through a LOT of clicks), add it and load the queue.
It takes WAY to many clicks from the homepage until i have a new album loaded 
There is a confirmation box whenever you add to the playlist, now thatīs annoying.
In general I find that the Media Manager has become a lot worse than before. More complicated, more clicks required, bad overview and problematic to use while driving.
I simply donīt like the bright grey color of the skin, but thatīs a one man oppinion
I just think the skin looks kinda "cheap" with that "easy-on-the-eyes-cool" blue, and that cheap 80īs plastic grey
I know this is a first, looking forward to bugfixes, an official ToDo list and all the plug-ins
