In the Defect Tracking module there are two locations where an enhancement is requested to enable the use of custom fields.
The first location is the search criteria for displaying defects. The enhancement would allow custom fields to be selected as part of the search.
The second location is the list of defects that show as a result of clicking the search button. The user can select some columns to display on the list. The enhancement would allow users to select a custom field to display as a column on the list.
