I would like to request the ability to scroll through the qr codes for a particular entry (flight, ferry, etc).
I usually add all the boarding passes for my whole family and I have to scan all of them at the gate. But it's very hard to switch between the qr codes as you have to click on the drop-down, select a new name and scan the code.

It would be a lot simpler to scan multiple qr codes if you could swipe left/right on the qr code itself so you could move next/previous in the list of qr codes. 
Or if swiping isn't possible you could just clock on the qr code, but swiping would be preferred.
