Shopify Order Printer

Love the convenience, but would really love to be able to request an upgrade to the format of the receipt and I do not know how to do that--maybe making that easier is itself an improvement that could be made.

The issue I have is that the receipt is formatted such that if someone orders multiple items, the price that shows for each item above the grand total is just the unit price (3 units at $6 is $18, but the column of prices above the total just contains $6 even though the grand total is correct). I've received a couple comments on that and I myself don't have the ability to change it. I'd like to make use of this, but continuing with this issue in the receipt is going to make it difficult for me to do so, unless I find a way to manually edit each incidence of this...

The templates contain metafields but there is nowhere to edit the metafield content.
A VAT invoice should be sent automatically to a customer at the time of payment (Should be part of standard Shopify) - This doesnt happen, so tried to create a Flow, there seems to be no automatic way to create an invoice and email the PDF to the customer.
These are basic ecommerce requirements that should have been in place with Shopify since they launched and should not need an app (or multiple apps) to work.

Love having a way to print a pick list, but why stop at 50 orders?? We have two print 2 or more pick lists which defeats the purpose. Please let us select more than 50 orders!!
