I had asked a question awhile ago about packaging an app with drag-drop ability in Unity:
It was closed as misplaced, should have been on the Ubuntu stack-exchange.
However, I have seen numerous questions on iOS/Apple, even some specifically related to packaging, that are not flagged or moved to http://apple.stackexchange.com.
for example. I was wondering if there is a specific policy about when a packaging question should be flagged/moved to the Android/Apple/Ubuntu/etc. site?
