Ability to shut-off online ordering for specific days, like Christmas
As far as I can tell, you can only set online ordering based on the day of the week, and not close for specific days. This is a problem when you allow orders to be scheduled for future dates, but will not be open for specific days.

This would help auto close the online orders for Christmas and other holidays. So merchant doesn't have to go in there every holiday and turn off, and then back on.
