Logs of conversations assignment in UI

We use balanced assignment and our team is not that big. This leads to situations when some conversations may stay in queue for a very long time without being assigned. Team activity logs does not show full information when the user went inactive due to closing tabs or smth and conversation events do not show any info about whether system tried to assign it to someone and what the verdict was. This will give much more visibility into how conversations are assigned as well as provide tools for performance and shift management.
