Yeah, I just always liked the idea of those four things being there on the bottom, always available.
It's weird...looking at the Safari icon, it hits me just how goofy and out-of-place it looks. I never noticed before. Why is it white around its perimeter like that? I guess they want to emphasize the round, compass motif? But if you think about a real compass, its face is often white (like a watch). I'd reverse those...I'd make the outer icon edge blue with a white compass face.
But they didn't ask me.
