I’ve been using the Safari 4 beta for some time now. My opinions of it are mixed however. I really like the new Top Sites feature. The Top Sites feature shows you the sites you visit most when you open a new tab, with a quick preview of them. This is what it looks like:

I also like that the keyboard combo control tab now switches to the next tab. However, it also misses the mark on some points. I always want to see a loading bar, so I know how far the page is done. Guess what, it was gone. The only thing that’s there is the circular loading indicator, totally worthless. I also didn’t like the new tab placing. If I hold the mouse button by accident when clicking on a tab and then move it, it’ll shift my window. That gets irritating after a while. But, i managed to get these 2 minor irritations fixed. Read on for the how-to

To get the loading bar and the circular progress indicator back, open terminal(/Applications/Utilities/Terminal.app) and type the following:
defaults write com.apple.Safari DebugSafari4IncludeToolbarRedesign -bool NO
Then hit enter. Then type this:
defaults write com.apple.Safari DebugSafari4LoadProgressStyle -bool NO
and hit enter. To apply these changes, just quit Safari and start it again.
If you want to reposition the tab bar, to where it was in safari 3, under the bookmarks bar, type:
defaults write com.apple.Safari DebugSafari4TabBarIsOnTop -bool NO
and hit enter. To apply this, also just quit Safari and start it again.

That’s it! You now have your loading bar back, the tabs can be where you want them to be and you still have the top sites feature! If you have any questions, just ask in the comments.
