You can make it look more like 3.x by moving the tabs to the bottom of the header. Took me a bit to figure out how, but you can almost make it look like 3.x.
It does seem way faster.
Also, right mouse button on the left and right arrows will allow you to see the last 10 pages you visited. Took me a minute to figure that one out as well.
How do you do this? Trying to find the tabs in the clutter of the header really annoys me. When they are on the bottom of the header, they are much easier to keep track of.
