[Plugin: WordPress 3 Invoices] Features request

Hi Elliot,
two little additions for a better management of invoices:
Custom issue date. Sometimes need to issue an invoice with a previous date, by now this is impossible, only current or future date are allowed.
A little textarea field “Note” at the end of Project Breakdown could be very useful.
Thanks a lot for this plugin
