Shopify Order Printer

I really can't see ANY benefits to this new app. We copied our templates and it's unusable. After a few hours we had got it almost back to as it was by changing the variables. Luckily I know a bit of liquid coding but I know many do not. What was the point in that in all that work - what have I gained? Shopify say there is going to be a migration tool coming soon... I don't think it can come soon enough.
