I can definitely see the point in this and we are interested in hearing how we can improve our system.
Currently we display create and resolve events in the "system events" tab on each device, including the ticket number. The list goes 7 days back.
Would a direct link to Zendesk be of use here?
Does the 7 day interval fit your needs?
Actually we do have a link to the associated ticket in Zendesk from the issue details page, but this is of course only accessible as long as the issue is open.
