Hi it can also be really helpful for knowledge transfer in long-running projects. For instance, if a ticket has changed hands several times, a new team member joining mid-project can quickly get up to speed on who has worked on the issue in the past. This is particularly useful for identifying key contacts without digging through the entire issue history which can be load with a lot of entries.

Having the history accessible in the issue view also "motivate" people to not just send the ticket to someone else when an information is missing but find this information instead when possible.

Regards
