Gradebook

Good idea Elena. I considered doing this at an earlier stage, but it looked bizarre when the aggregation position is set to "First" in the course gradebook setting, and I really wanted the colour to delimit clearly the boundaries of the category. Right now I am using an extra row of empty coloured cells, which looks good but is not very good HTML markup (I'll probably get teased by someone about that), for accessibility reasons etc...

I'm not yet sure what is best here, but I agree that, if aggregation position is last, your suggestion is the best.
