The keyboard shortcut for the search box should be Cmd-Opt-F as in Safari and other apps. Im not sure if this is an undocumented shortcut, I use it a lot.

Safari use a single button for stop/reload, displays page loading progress in the address bar and can be used without a status bar(OW has buttons in the status bar). Are this considered bad things? I love them! Having different buttons for stop/reload seems as silly to me as having an iPod with different buttons for play/pause. Having a spinner seems well, throwing away screen space to give less information than a progress bar.

Overriding commonly used shortcuts like Cmd-Up is a big no-no for me, Safari does it for Cmd-Left/Right and I hate it too. I keep getting tripped by this.

No smooth scrolling!
