I need to put more data in the QR template

{product_name1}{product_qty1}{product_subtot1}
{product_name2}{product_qty2}{product_subtot2}
{product_name3}{product_qty3}{product_subtot3}
{product_name4}{product_qty4}{product_subtot4}
….

ok I will do it as you requested upto 50 items
but I think better to have 3-5 variations like this ( I will add later these variables too ):

{wc_order_items_template1} =
Name Qty Price Subtotal
product_name1 ( 5 X 50 = 250 )
product_name2 ( 3 X 15 = 45 )
…

ok, that would be great!, thank you very much!

Its done !
Please re-install plugin you will have new variables as you wanted
Go to wordpress settings there is short explanation.
Documentation will be ready little bit later after few days
