Safari 4 hidden preferences
There's quite a debate going on in the Mac web over Safari 4's new user interface. Personally, I think the new tab implementation is hideous, so I was glad to see that Caius Durling has discovered a bevy of hidden preferences for Safari 4.
With a few quick Terminal commands you can restore sanity to your tabs, bring back the old URL completion behavior, remove CoverFlow from the Bookmarks view, and few other neat tricks. On the other hand, if crazy tabs float your boat, they're easy enough to restore in the same way.
