A constant theme in the 2 years I've been using appcode has been discovering new features by chance that make me go:
"wow - these guys really really understand software development on iOS".

I have no idea when you did it; but it's yet another gem, in a treasure-trove of awesomeness.
I love you guys : you make my day to day work so enjoyable and productive.
