The new UI that just appeared at the top has several serious deficiencies.
The most important are is that the links to [meta] and [chat] are gone. It is now almost impossible for new users to discover these features. Similarly, the link from meta to quickly navigate back to [main] is gone.
I strongly urge that these links be restored to the bar.
I also think the high tech styling at the top of the SA more traditional skin is very disconcerting, but that is only an aesthetic issue.
