When you first login to GQueues you are given a couple of categories to get you started (Home and Work). Feel free to rename these, delete them, or add more categories.
Choose Add Category from the menu to create a new category and give it a name.
(You can also use a keyboard shortcut).
Click the (+) button to expand a category and view the queues it contains. The (-) button will collapse it again.
Click and drag the category name to change its order.
Hover your mouse over a category and click on the menu button to Rename a category, Delete a category, or Add a Queue to a category.
You can print all the queues in a category by choosing Print queues from the menu.
You can sort all the queue in a category alphabetically by choosing Alphabetize queues from the menu.
