Via Dave Marra on Twitter, here's a great tip for tweaking the latest version of Safari. You know, now that it has developed this irritating iOS-like habit of hiding the full URL from you in the address bar? Yeah, we can totally fix that. Here's how: Go to Safari > Preferences > Advanced and check the box for Show Full Website Address.
Safari's Advanced Preferences.
That's it! Now you'll get the entire URL in all its glory, as God intended.
