Knitnstitch review for Retail Barcode Labels

I don't mind the number of screens, and I had no problems getting this app to function, but the following would really help 1. ability to print just one variant( we have products with 100 variants and its too hard to set all the quantities to zero for the ones you want to suppress) 2. the ability to print barcodes from a Shopify transfer using the quantity you are putting into stock (ie when receiving new stock and doing it via a transfer) 3. the ability to scan an existing barcode into admin- you can only doing this by putting the scanner into keyboard mode (which is pretty tacky). 4. the ability to shrink fonts when product name or variant titles are long.
