Rename Estimates as Sales Order
Currently we use Estimates as a way to enter a customer purchase order. We manufacture to order so we aren't selling off the shelf. We changed the template to properly read Sales Order but the email confirmation still requires the word 'Estimate' to be in the subject line which confuses our customers who want a sales order acknowledgement.
The suggestion is to allow the Estimate to be renamed and used as an open Sales Order.
We also have a template named Quotes which is more what Estimates was probably designed for. We need both a quote form and an acknowledged Sales Order form with respective email subject lines.
