We had an issue where we could not figure out why an approval was assigned to someone, when it never should have been. We couldn't see what the normal supervisor had their Out of Office set to (see my other recently created Feature Request for audit tab on Account screen) and the audit tab of the change ticket just showed it was assigned to the guy that it shoulnd't have been.
If there's an out of office reassignment, it would be super helpful when we're trying to track down why something happened, to have this information in the audit tab. Because as things stand my users just trust the process we carefully crafted less than they did before.
