The minimum column width in the Gradebook is going to be a major problem for me and others who have commented in the Production Notes and questions here.
I have many, many small graded assignments. Good online pedagogy encourages that - lots of small-stakes work, scaffolded learning, multiple opportunities.
I have designed the beginning of the names of these assignments to be two or three letters long so I can squeeze the columns as tight as possible and see grade trends for the class at a glance. It will really slow down my workflow to be continually side-scrolling and/or reorganizing columns between "by due date" and "by category" just to see the patterns.
