Hm, for me it was clear that "Course Settings" were only affecting one gradebook at a time.
How about Course Gradebook Settings?
But then, we have "My Report Preferences" tab which influences view on the user-basis. And it is located right near Grader Report.
It would make more sense to put "Course Settings" there instead.
Plus, add "Categories and items" there too, since this one is very strongly related to the "Grader Report"
Though, I would rename again: Categories and items -> Calculations.
I will try to create a sample mock-up for tabs and lang changes (It will probably take me couple of days)
