If there is not a way to do this, it would be nice for it to be considered for future development.
Is there a way to edit the assignment display name in the gradebook. For example I would like the name of a quiz displayed as: Quiz 2: Multiplying Fractions, but in the Gradebook it could be simplified as just Qz2. I find the gradebook difficult to read when you get lots of assignments in there. It would also be nice if each column could be a different shade of gray, to break things up a bit. Simplifying the gradebook display name would help a lot.
Would be great if this could be integrated in to gradebook v1.9.5!
