I'm liking the new color scheme. Good contrast and very easy on the eyes.
I'm intrigued by the USB symbol on the bottom left - perhaps has something to do with the synchronisation status at the bottom?
When viewing the sample screenshot it wasn't zoomed in 100% so the new menu placement seemed a little hidden away. A full-size viewing put that doubt to rest, the new placement works.
The interface for v6.X worked well, but I'm loving this one better. Clear, clean and very professional.
I'd also like to add a +1 for an improvement to the search responsiveness.
