You can drag the columns anywhere you want as OAH suggested. And also resize them if prefered. And don't forget to do this Arrange search results by size (click on link) so you get the largest files at the top of the list.

I arrange files by various techniques depending on what I'm wanting. eg: I may arrange by size, I may arrange by #, or I may arrange by status, or I may arrange by quality or progress in both the search results & downld window. Arranging by quality will let me know which ones I haven't downlded or which ones are the highest quality connection, etc.
