John Gruber’s thorough ‘observations, complaints, quibbles, and suggestions regarding the Safari 4 Public Beta’ is a great read for anyone interested in interface design – regardless of their OS or browser preference. (He also mentions my suggested design for the new Safari tabs.)
He summarizes my main beef with the tabs:
Consider: with the previous tab design, if you wanted to move a window you dragged the window, and if you wanted to move a tab, you dragged the tab. Now in Safari 4, if you want to move the window you drag a tab, and if you want to move a tab you drag the small grippy strip at the far right edge of a tab. This is more abstract, indirect, and worse.
