Often a case in FogBugz is closed, but needs to be re-categorized under the appropriate project, area, or parent case. The person who closes the case may not care about the category as much as a project manager or administrator who wants to see the cases organized a certain way. Re-opening a closed case just to correct data like this throws off any value that the Resolved Date or Closed Date fields might have had regarding the actual resolution of the issue.
Is there a way to get FogBugz to allow milestones, projects, areas, and parent cases to be edited after a case is closed? Perhaps a plugin could be used for this purpose?
