It would be nice if it were one of the notifications that tells you what's losing the state that you're gaining. I suppose it's worth filing a bug requesting that; the last active app is a useful thing to know. I dug into this because when I put up a dialog saying that an inter-app operation failed, I wanted the activation to go back to the app that started the operation when the dialog was dismissed.

Glad to hear it was helpful anyway.
