MX Merchant Ideas

I've had multiple clients request this.  Currently capped at 8 characters I believe, there are many whose invoice numbers are greater than that, especially if they are a long established business. 

Also, I have many clients that will do an invoice for a deposit and a balance, and will use the same invoice number with a D for deposit and B at the end for balance.  It would be great if we could sort based on a "free text" look up in the invoice field.
