Currently, when applying a payment to help lower a parent's monthly payment, there is no way of seeing what the new payment will be without actually putting a payment all the way through. It would be nice to have a "Preview Allocation Impact", "Preview Impact to Payment Schedule", and "View Current Payment Schedule" Screen.

It would also be helpful to have the totals on the "Edit Billing Details" page to calculate and adjust as line items/amounts are being added, instead of not updating until you save and leave the page.
