Once you start working with the product and develop a workflow where you are assigned tickets on a regular basis, you require an organized queue of the ones that need your attention. This is called a "view" - when you get tickets assigned to you, a filter can be applied by choosing "me" in the agent field and other properties could be changed to see your prioritized list. 

Say, for instance, you are an agent who works on social tickets on a high priority - please choose this in the filters on the left of your ticket queue. Once this is done, you could see the header of the queue changing with a tick mark followed by three small dots which could be clicked upon and save it as "Alex's social tickets."
