• GUI-Support The installation of this tool will register a new button in the Design section of MeerK40t:

If you click on it then a dialog will pop up allowing you to design a qr-code / a barcode:

This will create an element in Meerk40t that can be treated like any other regular path, but which will allow post-creation change of the underlying code (ie the barcode will be regenerated based on the new input).
