Here’s a hint I know our team wishes it’d known for awhile. In Safari 4 and WebKit’s new Web Inspector, you are currently able to edit styles, but not add new ones. A workaround is to edit an existing style, and add the new style after the semicolon. When the field loses focus, the Inspector will automatically move it into its own field.
One of our teams has been diving into Facebook Connect and put together this collection of resources for us. Are we missing anything?
