QR tags are too complicated

[AaronDB2]

The QR tag generator ( https://modx.com/extras/package/qrnfcgenerator ) generates tags that are way too complicated. This because of the UTM tags that are added for use in Google Analytics. It would be better to give users the choice to add (custom) UTM tags so they can generate cleaners QR tags also.

Another way is to integrate a shortener service.
