With the release of Safari 4, many people have been asking how to move the tabs back to the bottom, where it originally was. I did some searching and found this site http://swedishcampground.com/safari-4-hidden-preferences. The site has been up and down over the past couple of days, so I have copied it below for your reference. All credit goes to swedishcampground.com.
Safari 4 Hidden Preferences by Caius – 2009-02-24 16:11:05
Having a quick poke through the new Safari binary yields the following strings:
$ strings /Applications/Safari.app/Contents/MacOS/Safari | grep DebugSafari4
DebugSafari4TabBarIsOnTop
DebugSafari4IncludeToolbarRedesign
DebugSafari4IncludeFancyURLCompletionList
DebugSafari4IncludeGoogleSuggest
DebugSafari4LoadProgressStyle
DebugSafari4IncludeFlowViewInBookmarksView
DebugSafari4TopSitesZoomToPageAnimationDimsSnapshot
DebugSafari4IncludeTopSites
NB: Run these commands in Terminal.app and then you need to restart Safari for them to take effect.
DebugSafari4TabBarIsOnTop
This moves the tab bar back where you expect it to be:
$ defaults write com.apple.Safari DebugSafari4TabBarIsOnTop -bool NO
DebugSafari4IncludeToolbarRedesign and DebugSafari4LoadProgressStyle
When both set to NO it restores the blue loading bar behind the URL. Also puts a page loading spinner in the tab itself, which looks odd with the new tabs.
$ defaults write com.apple.Safari DebugSafari4IncludeToolbarRedesign -bool NO
$ defaults write com.apple.Safari DebugSafari4LoadProgressStyle -bool NO
DebugSafari4IncludeFancyURLCompletionList
Switches off the new URL autocomplete menu and goes back to the original one.
$ defaults write com.apple.Safari DebugSafari4IncludeFancyURLCompletionList -bool NO
DebugSafari4IncludeGoogleSuggest
Turns off the new Google suggest menu.
$ defaults write com.apple.Safari DebugSafari4IncludeGoogleSuggest -bool NO
DebugSafari4IncludeFlowViewInBookmarksView
Removes CoverFlow from the Bookmarks view entirely. (Credit to Erik)
$ defaults write com.apple.Safari DebugSafari4IncludeFlowViewInBookmarksView -bool NO
DebugSafari4TopSitesZoomToPageAnimationDimsSnapshot
Disables the dimming when you click on a Top Site and it scales the screenshot up to fill the screen.
$ defaults write com.apple.Safari DebugSafari4TopSitesZoomToPageAnimationDimsSnapshot -bool NO
DebugSafari4IncludeTopSites
Disables Top Sites feature completely.
$ defaults write com.apple.Safari DebugSafari4IncludeTopSites -bool NO
Undoing changes
Just run the defaults command with the delete flag for the appropriate key you wish to delete.
$ defaults delete com.apple.Safari
