If you go to Cases > All Open Cases, there is a column for Owner, which displays the CCO ID of the person who opened the case. It isn't always easy to determine who the CCO ID belongs to, so it would be helpful to have a column for owner's email or name.
If you click on the case to view the summary, it seems the owner's e-mail address does appear there, but it would be quicker to have that appear on the list view as well.
