Safari 4 opções escondidas

Embora algumas das novas funcionalidades do Safari são novos para o browser (por exemplo, Top Sites Pesquisa e História), outros são modificações das funcionalidades existentes (ex.: guias em cima).
Infelizmente, a Apple não oferece opções para personalização desses elementos, embora estas
opções existem.
. Aqui está uma lista das opções conhecidas escondidas no Safari 4 Public Beta:
Para executar esses comandos, copie e cole-los na Terminal.

All of these commands are "boolean", which means they take either a "YES" or "NO." Ss such, to revert them just re-enter them in the terminal with "YES" (the default value) at the end.
Change Tab Locations To change the location of the tabs from being in the toolbar to being under the URL address bar, enter the following in the terminal:
defaults write com.apple.Safari DebugSafari4TabBarIsOnTop -bool NO
Bring back the blue loading bar The new "loading" indicator is a spinning wheel at the right side of the address bar. This shows activity but doesn't indicate progress, and, as such, has some users wanting the old style back. The following two commands will bring back the blue indicatory bar that displays behind the URL.
defaults write com.apple.Safari DebugSafari4IncludeToolbarRedesign -bool NO
defaults write com.apple.Safari DebugSafari4LoadProgressStyle -bool NO
Turn off the Google search suggestions When users enter search terms in the Google search field, suggestions based on popular searches will display. Users can turn this off by entering the following command:

defaults write com.apple.Safari DebugSafari4IncludeGoogleSuggest -bool NO

Revert to old URL completion behavior The previous URL completion mechanism would grab any reference to a URL and try to complete it for the user when URLs were manually entered. These could come from History as well as Bookmarks, but the completion was rather crude. In Safari 4 these auto-completions are displayed in categories, so users know where Safari is referencing them from. If this behavior is undesired, users can revert to the old completion list.

defaults write com.apple.Safari DebugSafari4IncludeFancyURLCompletionList -bool NO

Disable "Top Sites" The new "Top Sites" feature is a snapshot of frequently visited websites, which also displays update indicators for the sites. This is accessible by default as the new page view (instead of a home page), or by clicking the grid of squares to the far left in the bookmarks bar. To disable this feature, users can enter the following command:
defaults write com.apple.Safari DebugSafari4IncludeTopSites -bool NO

Disable "Cover Flow" in bookmarks manager Apple really likes their "Cover Flow" feature, which started in iTunes and made its way to the Finder and now to Safari. Users can minimize this by dragging the separator bar up to the top of the window; however, users can also completely disable it by enter the following command:
defaults write com.apple.Safari DebugSafari4IncludeFlowViewInBookmarksView -bool NO

Change the dimming behavior of Top Sites This is relatively trivial, but by default when users select a page in "Top Sites", the view of the page will dim while Safari accesses the page and updates it. This provides a visual that the current view may be "out of date" and when the page brightens up it will be showing the current page contents. If users don't want this dimming behavior, they can disable it with the following command:
defaults write com.apple.Safari DebugSafari4TopSitesZoomToPageAnimationDimsSnapshot -bool NO
