It would be nice if when you mark a registrant as paid you could add how the payment was made- check, cash or etc. The integrated paypal option is great but I have many registrants who need to have their district pay via check. I also had to invoice a few people via paypal as a different individual was responsible for payment than the registrant. So I I had to start a separate balance sheet to keep up with payments. Having this integrated would be very handy. Just a blank spot to write a note would be sufficient.
