Never cared for autohide on taskbars etc, I find it distracting to have things moving in and out. However, I do have two high resolution monitors and therefore like having a real menu bar, and real statusbar. Please, browser makers, quit trying to make that difficult.

Although one thing I'd like, which I've seen no one implement yet is to have links urls as tooltips on mouseover. Perhaps below another tooltip if it existed. Shorter distance to move my eyes.
