Since you already have data fields for case status, type, priority, label and department--I'm assuming there are future plans to be able to aggregate data based on these fields (as well as meta data like date opened, etc.) There are a myriad of ways this could be implemented, but without that functionality, those fields really have limited use.
As a simple example, it would just be very useful to be able to view all tickets containing a given label grouped and/or sorted by priority or status.
Thanks for considering--you already have a great app!
