The new minimum column width causes enormous problems for those of us with many assignments, who shrink the width, manually, to try to see more of the grades.
For example, I have many, many small graded assignments. 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.
Please restore the capability to manually adjust column width in the gradebook.
