The page loading indicator in Safari is obtrusive and not very intuitive-the address bar fills with color from left to right. For a company that prides itself on elegant design, this is anything but. With Safari 3, there is a new optional page loading progress indicator option available. Instead of coloring in the entire address bar, it uses a pie chart to the left of the URL in the address bar. Here's a picture of what it looks like in action:

If you'd like to make use of this more elegant page loading indicator in Safari 3, close Safari and open a terminal window (Applications -> Utilities -> Terminal). In the terminal window, enter the following text and hit return:

defaults write com.apple.Safari DebugUsePieProgressIndicator -bool true

You can then close the terminal window. Next time you open Safari, you'll get the nicer looking progress indicator. If you change your mind and want to revert to the old Safari progress indicator, just repeat the process and replace true with false.
