After creating a QR Code, there is this big green button with the word "Save" on it. Suggesting that it would save you preferences. This is not the case. Please fix / create this feature so all our employees can save time making use of it. Having to re-do QR-codes several times a day is a time waster.

Global settings for this would be even better.

Other than that, we love your product and our now using it across our 400+ employee company.
