I've read through all this, and I'm still not sure if the Alt-click-to-trade feature is coming at all, or not. It's in Postman, as the only feature Postal doesn't have. Copy/paste? :P I know you would never do that, though. Anyhow, I've downloaded that standalone addon for it, so no worries. Just curious.
