Whenever you edited with the Nexus 4's photo gallery app it would save it as a copy, leaving the original behind. Andrew's article about the new KitKat version mentions it's non-destructive, but I've discovered that when I've edited photos, it's NOT saving copies, but replacing the originals with the new edited versions, destroying the original in the process. I'm lucky I didn't nuke anything important, but I don't get what's going on here? How come everyone is calling this new editor "non-destructive" when it's totally destructive? And why doesn't it look like the pictures? It looks like the old N4 one, but now makes hash of your originals. Anyone else seeing this?
