The new top bar is very unintuitive. Sure it works for all of us, because we're used to SO, but new users will be extremely confused by this new, less featured design.
New additions should add features, or remove unwarranted/deprecated features. This addition has removed many useful features, does not match the site layout at all, and is absolutely sure to increase the number of confused new users.
IMHO it should have many many more features in all of the empty unused space, not less. Use the space you have to your advantage.
EDIT: This is not a duplicate, we were specifically told to start new questions with the top-bar tag in the original Meta post. Which is what I have done.
This is an incredibly simple change
.. according to who ? Also might I re-ask what the missing features are ? With such a promising title, I expected a little content.
