Finally. I like it. Can’t wait for a final release. John Gruber (Daring Fireball) laments:
… I can’t stand how the close button for tabs is on the right. On the Mac, close goes on the left.
Well, close goes on the left, of Mac windows. FireFox also seems to be okay with the close button on the right for tabs. I personally don’t mind since I haven’t used Safari in a while.
