If you would like to distinguish your custom queues from the default ILLiad queues, you can create a category to display the custom queues separately from default queues in the Requests Group.
For instance, in the Borrowing module, you can create a category called Custom Sort Queues, for your custom queues. When a request is moved to one of your custom queues, it will automatically display under the Custom Sort Queue category. When there are no requests within the queues under your category, the category will not display; when requests are added to those queues the category will display on the Client interface. Customizations are automatically saved for individual users, and can also be saved to a file, shared and adapted by other users.
