Would you be able to allow the collections list to split over multiple lines ?
collections=[
["Holidays", "18E8-591DA800-7A3-2A142940", "holidays_shared_by_system"],
["SiteWorks", "3E5-5B06C580-7AB-791F1F80", "site-works_shared_by_system"]
]

and allow tabls and new lines ?
It would greatly improve reading of the config file.
