@ bombastic bob
I am interested by your reference to IBM. First of all, because I still have the DOS 1.0 manuals I got with my first-ever x86 PC, and I still hold those manuals to be the best ever written manuals that I have ever read. Clear, concise, understandable and useful. There is not one useless page in that manual.
Second, because I clearly remember a Microsoft paper that was circulated in the 1990s (well, after 1995) where I was told to pay attention to the GUI elements, and I specifically remember notes about paying attention to color codes (red does not hold the same significance for Western cultures as it does for other ones) and, most importantly, a rule that was drummed into our heads : if your menu depth goes beyond three levels, You Are Doing It Wrong (TM).
Unfortunately, I did not keep this piece of history, but I still remember its precepts.
