Currently, the Get Next button obtains the oldest item regardless of queue.
If a tech is a member of multiple queues, the Get Next button should only pull from the queue currently selected.
Example, a tech is a member of queue 1 queue 2 and queue 3. Currently queue 2 is selected and the oldest session in in queue 1. Since queue 2 is selected, the button should only pull out of queue 2.
On the same token, if "My Queues" is instead selected, the Get next button would pull the oldest of those displayed.
