I've just uploaded v1.0.0-FINAL (downloadable here, when available: http://www.zen-cart.com/downloads.php?do=file&id=1823) to the plugins. This version
  1. Corrects the formatting of order-confirmation emails
  2. Corrects the "misspelling" of a variable name
  3. Includes admin-console changes to the formatting of invoices and packing slips for multiple ship-to address orders
  4. Includes admin-console changes to allow sub-order status values to be independently changed.
