"It looks like it supports a long-time pain of being able to direct someone to download an app and then open a specific location within the app. You could now have a QR code that when scanned from a shop didn't just download the right app for the phone, but the applink would also describe what to open once the app is installed."

Is that what it actually does? If I have an iTunes url to my app can I imbed an argument to send to the app once it runs after being downloaded? I would have thought a standard requires implementation by apple for that to be the case.

Ive read the fb post, saw the f8 section and watched their video and I still don't know what it does. Maybe Im dim.
