Finder 10.3
OS X v10.3 ("Panther") introduced a somewhat upgraded version of the Finder which restored several classic features while also introducing an updated, but not radically different, GUI.
Finder 10.3 took on a Brushed Metal appearance similar to that of Apple's iTunes jukebox application (before version 5, which took on a Polished Metal look), or Address Book before OS X Tiger. As with previous Finders introduced since OS X 10.0, users could customize a toolbar at the top of the Finder window. This included a search pane, allowing for live searching of any selected folder or volume. A new panel to the left of the Finder window, called the Sidebar, allowed almost any item to be dropped in for quick access. Importantly, this customisation would appear in open and save dialogs within other applications. The Sidebar also listed and allowed the ejection of mounted removable storage. Colored labels and the ability to search by Type and Creator metadata, features in Mac OS 9 that were lost and much missed by Mac users, were restored in Finder 10.3.
By clicking the small "show/hide toolbar" button on the right of a window's title bar, not only could a window's toolbar be hidden, but the window also removed its sidebar and switched into an Aqua-themed look and "spatial" behavior. The animation for the toolbar disappeared due to the sidebar as well.
