The way to receive a payment and apply it to a customer's invoice is a basic function that has not been fully developed in Gnucash.

Currently there is only one convoluted way to process a payment, and that is through the top menu only. One has to manually find the invoice and do several clicks. If you have multiple payments to receive, this is a rather sloth procedure.

I'd like to request the following features that would improve a very fundamental function:

1) In the 'Customers' window, place a button on the toolbar labeled 'Process Payment'. When a customer is selected with a balance, pressing the button would bring up the Payment Process dialog with the client already selected.

2) In the 'Customers' window, add a right-click contextual menu item labeled 'Process Payment'. It would serve the same as the above mentioned button.

3) Add a 'Process Payment' in the toolbar for the Account Receivables window.

4) Add a 'Process Payment' contextual menu item for the Account Receivables window.
