One feature request I have based on user feedback is for the queue buttons that are collapsed into summary mode to also include the Call Waiting Timer of the first/longest call in queue.

i.e. Currently the summary shows Agents and Waiting Calls only. The request is to have one more line that has the timer.

That way it is would be very easy to see the wait times across all your queues in a nice compact screen without having to expand each button into its Detailed view (which can take up a lot of real estate on the screen).
