I agree wholeheartedly with not having the icon in the same spot!
That is a training issue we struggle with new teachers all the time. We tell them to look in the administration block and depending on the where you are in the course it changes what appears in the block. Very confusing for teachers new to Moodle.
I even love that fact that the site settings/management of the course is only on the homepage of the course. This creates one way and one spot to go to turn editing on and manage your course. Makes training great!
