Would also be nice to be able to:

1) alter width of columns by dragging the separator line in the header row
2) drag column headers to a view I prefer
3) ability to edit the viewed columns (adding further columns would be nice here)
4) ability to save my setting so it returns each time my user goes to this screen.

This kind of applies to any page with a table to be fair.

I don't know if we'll use it for sure, but #4629 is about using Patternfly which has a variable width design.
