I have some good news - users can filter the agent list in the real time Queues Activity Detail views by ACD skills and languages later this week. We are almost finished scoping out teams, and will most likely start that work early next year. I'll make sure I touch base with the consulting team with those requirements. Filtering agents by tags will shortly be available in very limited release to a limited number of customers, but we'll be expanding that functionality into Ad Hoc teams next year.
