Thank you so very much indeed.
It's partly the programmer in me and partly the designer in me. I often work where I'll have an application in the background and I'll want to open a file with it. With the Mac OS/GEM style menu, you activate the application, then select from the menu. With many other GUI systems, you click on the menu selection, the application is activated, and the menu option is selected subsequently.
My first GUI experience was with the original 128K Macintosh, but my first long term experience was with the Atari 1040ST and GEM, which could be described as a work-alike.
