Even though there is no such thing as Queues in GLPI, when talking about tickets, you can use a virtually unlimited number of views and treat them as Queues.
Here is an example of the most requested "queue" among our customers:
This view is useful when a group of support agents pulls tickets as they come (instead of a push system when a ticket is assigned to an agent through automatic rule or a supervisor).
You can save a filter as a bookmark by clicking the star next to the clear filter button. Provided enough privileges you can make the bookmark public or set it as a default view for all agents.
