Scenario: Case is created from a ticket and Aborted before completion. Another case is created from the same ticket and brought to normal completion.
If you go to the Search window and look for the case reference (choosing search of Work items) you will see the work items associated with the case reference returned. All are colour coded to black as they are all closed.
For a user it would be helpful that there would be some distinguishing indicator at this level as to which is the completed case (and its actions) ... and which is the aborted case (and its actions). Instead you have to open the work items to determine this.
