More available information when viewing the mobile event app would be extremely helpful - we have a number of situations where a father and son are both participants in an event and live at the same address - we are unable to determine which is which. Class year, email address and phone numbers would also be extremely helpful. Also, if someone is already registered for an event and wants to add additional registration options when the arrive at the event, it would be helpful to be able to do that within the existing registration, especially if using mobile pay so they are only making one payment.
