It is a nice redesign but it is too bad you didn't solicit some feedback in advance on some of the decisions. Clearly hiding the taskbar is huge. And is there really a problem with color? I'd prefer to not have all the icons gray and would like at least a couple color schemes to be available as before.
Lastly, you really should have sent us an e-mail in advance that a new design was coming. It is a great job and I, along with the many other people posting, am glad to see you putting the effort in to keep this a great product / service. But please give us advanced notice in the future via e-mail.
