Added a new Umbrao Automate package to the marketplace. This one will generate QR Codes (base64PNG or SVG). It also comes with a QR Code Viewer Property Type, so you view the QR code in the backoffice. Also comes with a handy TagHelper to render in the QR code in a View. There's also an action to optionally save the QR code as a media Item. Check out the screenshots on.
