Please, please keep the data card and make it work correctly. I think the only reason I keep using 2xx is because I can do all my tasks directly from the data card.
It's so much easier to enter the payment received info on the data card. I hate scrolling and it makes me dizzy!
I also wish the "search status history" function worked. Another good thing would be to have invoices like in 2xx. Then I would be a happy camper!
