A 2D or 3D dock!
A lot of people complained about the look of the new 3D Dock, but even more so, of the lack of choice for the look of the Dock. The side dock was supposed to be 3D as well, and it only changed in the Gold Master. What is great is that every time people are unhappy about the look of the OS, a third-party application solves everything and this time is no exception. It is called CustomDock. It is a very simple application that lets you switch from a 3D dock to a 2D dock and vice versa. From what I understand, it should also let you get a side 3D dock (I am not sure, I haven't tried it, I really like the new Dock!).
