A gap that existed between GBNG (and Gradebook) was to include an item in the final grade but not have it visible to students. We've had a request for that feature to be re-implemented.
It seems like based on the discussion on
It originally briefly worked like this and there was some use case for it, but this was changed to work the opposite. I feel like in GBNG it's more clear which columns aren't visible to the student, and the only change this would really involve are all of the checks around the "Add gradebook item" page preventing these options from both simultaneously being checked.
Though I do believe if it WAS implemented, it should be made clear on the student view that the course grade included items that were not visible to them.
I marked this as for discussion as I'd like to see what anyone else thought about this or if the design was just made to follow Gradebook Classic.
