Marketpress - Order cancellation - partial or full refunds | Also printed packing slips

Question 1: Is there a way within order management to cancel all or part of an order and have money refunded without going into Authorize.net and manually refunding the money?

Question 2: Is there a timeline on implementing/adding a new feature to allow printing a packing slip and/or invoice from the "Order Details" screen? We can download the CSV file and run it through a merge and print from that, but that's a huge pain...
