How do I include the client name on the task listing?

At the top of the task listing there is a checkbox to "show widescreen view". If the widescreen view is enabled three additional columns will appear on the task listing: client, module, and start date. You can click to sort on each of these columns. Also, if you click on the export to CSV link at the top of the task listing additional columns of information are included. This is true whether or not the listing is in widescreen mode or regular mode.
