Retail Barcode Labels

Perfect app for adding barcodes to all your products instantly. There is an option to generate barcodes for products that haven't got them yet (or rewrite all of them with new ones). I guess this last feature is causing some issues with other users (probably that's why the rating of this app is lower that should be, in my opinion).

The only option that I miss at the moment, is a way to define custom sized labels. There is a lot to choose from, but we need a really specific size. Could this be added, please? :)
