In the old days (MacOS 7 and 8 etc.) I often played around with ResEdit in order to change the appearance of windows, icons and what have you in an application. Having tried out Photoshop CS4 my first thought was how ugly its user-interface was. Specifically, the square tabs (layers, history, actions etc.). They look like something from the Windows 3.1 days or early Linux. Nothing that belongs on a Mac! I much more prefer the tabs used in CS3. Not being a programmer, is there an easy way to modify the above GUI stuff? Perhaps, provided the GUI elements are images (e.g. the tabs) I could maybe take them from CS3 and put them in CS4?
