Update: I've added the idea to the studio. Please vote if you would like to see this as a feature in the grade center. Thanks!
I have several columns in my Gradebook and many of the columns have a very similar title, so it's hard to tell at-a-glance which is which. I've turned on new grade book and appreciate that I can resize the column width. However, that's not a perfect solution because the grade columns return to default width every time I refresh the page. It's also tedious to have to resize all the columns just to see what assignment I am looking at. Aside from mouseover, it would be great if there was a way to create abbreviated column titles, so I could use a meaningful naming convention that fit the default column width in a way that I could distinguish assignments at-a-glance (i.e., mod 1 DQ, mod 2 DQ, etc.). Does this exist already? I couldn't find a way to do that.
