Gregg, I assume you know about using the option on the View menu to customize the Safari 4 tool bar. Have you discovered the item in Safari 4's debug menu that lists all of the keyboard shortcuts? I am amazed at how many there are. If you don't have the Debug menu showing MacPilot can turn it on or off along with at least three Safari 4 only options:
  • Whether the toolbar is at the top of bottom of the window
  • Placing the additional controls inside the address bar
  • Enabling or disabling Top Sites
MacPilot can't restore Snapback, but it might allow you to tailor Safari 4 more to your liking.

If we knew what it was we were doing, it wouldn't be called research, would it?
