I have just been configuring non-delivery days (public holidays) and thought it would be good if these were:
a) Enabled by default and
b) Automatically generated each year from the XML at https://www.australia.gov.au/about-australia/special-dates-and-events/public-holidays
This would save having to remember to do this each year and a lot of re-work.
This feature could be touched on in the documentation too, as I couldn't seem to find any mention of it.
