Order days grace option on payment gateway
Currently, the 'Order Days Grace' (The number of days to allow for payment of an order before being overdue) is a global setting. It would be good if this feature was moved or added to each payment gateway.
The reason behind this is that most people will have this setting set to '0' so that credit card payments etc are captured at the same time the order is processed. Setting it greater than 0 will mean payment won't happen until the due date (or whatever 'Process Days Before Due' is set to). So, by having this option as a per payment gateway setting, you can have credit cards etc set to 0 and things like bank transfers set to a great number to allow time for the customer to make payment.
