If like me you’ve been seriously annoyed by the page-load delays in Safari 4 (beta) then you may be interested to learn of this ‘fix’:

Go to System Preferences > Network > Advanced Settings > TCP/IP and change Configure IPV6 from Automatic to Off.

And here's a fix for those of you who also prefer your tabs back where they belong — below the Bookmark Bar.

Finally, if you really want to extend Safari's features, check out Glims.

[UPDATE] And here's a great new tip from regular RapidWeaver Central passenger Tom, who sent in this heads-up on Safari's Secret Tweaks Menu. Here are some of the options it enables:

• Tabs on Top - toggle between Safari 4 and Safari 3 style tabs
• Toolbar Redesign - toggle address bar having additional controls inside
• CoverFlow in Bookmarks - toggle CoverFlow
• Google Suggestions - toggle Google Suggestions when using Safari Search Field
• Fancy URL Suggestions - toggle between Safari 4 and Safari 3 address bar suggestions style
• Transparent Window - make window background transparent. This is only noticable for pages with no background set
• Top Sites Feature - toggle Top Sites feature on and off completely
• Top Sites Dimmed Animation - dim pages when opening them using Top Sites feature
• JavaScript No New Windows - toggle whether JavaScript can open new windows or only new tabs
• Don't Confirm Unsubmitted Text - don't show warning when closing a window with unsubmitted text
