I remember the first time I saw Preferences Panes in OS X. (See
Settings Menu)
After dealing with OS 7-9 (+ Rhapsody) multi-windows Control Panel Applications, this single window/Application UI seemed like a throwback to the pre-OS 7 "CDEV Viewer" Control Panels. (See the
General Controls on this page.)
See... Same UI except the CDev Viewer had a vertical list of "CDev's" while the Pref Pane was horizontal.
Anyone else around here old enough that they made that same connection?
