The QR Codes creator now puts the fields on the left and the preview, download buttons and save section on the right. The preview column stays in view as you scroll, so changing the kind of code, opening the design options or filling in a contact card no longer pushes the preview and the buttons down the page. Below 900 pixels wide the preview returns to its place under the fields.
The QR code preview stays put while you work
On a wide screen the preview and the download buttons sit in their own column beside the fields instead of below them.
