As I was missing the image names, it took me a while to figure out to drag expand the Image column so that instead of just seeing the image icon, I could also see the image name. When I double clicked on the column, I expected it to auto fit to the longest image name, but instead it makes the column very wide with a lot of empty space. I then tried the auto-size by double clicking on the other columns (Aperture, Speed, Iso and Focal (35mm equiv)) and they all do the same thing, except that the amount of blank space in the column varies.

Additionally, the Focal (35mm equiv) heading cuts off by default at "Focal (35mm equ".
