New Customer Flag
It would be great to have something on an order page that flags up if a customer is a 'New/First Time Customer'. That way we can include specific new customer promo material in their order or especially if it is a subscription order, this would allow us to add materials which don't need to go in everytime.

This would be useful, you could categorize customers based on their type (brand new, first time returning customer, long term, extremely long) and give them different marketing materials / coupons dependant on their level. Also use it for on the anniversary of their first purchase give a voucher etc.
