Coruscant

I would like to customize the widths of the Drive / File System / Capacity / Used / Free Space / Defragmentation / Status columns. I use Defraggler on a Full HD display with a DPI set to 125%. As a result, the Defragmentation column header as well as the contents of the Used and Free Space columns aren't completely displayed. The font is too big for the space provided. Currently, the seven columns cover only 40% of the screen's width but when I modify their individual widths, the changes don't get saved. It would also be nice to have every second row slightly shaded to provide contrast.
