iOS 7 can let apps call up presets in other apps!!
You heard it here first folks :-b
Aufx: space got an update today and one of the new features is:
"Use app-specific file extension for presets"
... Yes, I'm speculating. I'm sure Apple will tell us more in a few hours.
But it looks promising, I mean why else would presets have file extensions that are different depending on another app?
