NO, support hasn't vanished, but I think Blindside is pushing hard to get the new updated version out. Let me try to help

The TYPE box is the payment type and is usually the credit card name if you are refunding the money via the customer's credit card. It is the list which you can set via Admin>Localization>Payment Types. For example, I have added one called "Adjustment". You could add one called "Refund". It will not affect the credit card account because SO does not communicate with the credit card gateway. You have to do that separately.

The NUMBER box is supposedly the payment number which is at the beginning of the payment line. I find that nothing is entered when the customer pays via credit card, but a number is there when they use PayPal. Again, it just seems to be for reference purposes so you can enter whatever you like.

You can also do a refund or adjustment by using the "Edit Order Totals" popup and entering a negative amount and a reason of "Refund" or "Credit", etc

Hope this helps.
