Lists can be created and modified to be used in scripts and War Rooms. A list can contain items of the same type in any format that would be useful. These are later parsed by, and can be modified by, scripts. For example, you might need to create a list of emails, a list of known trusted IPs (allow list), JSON objects, etc.
