Shortening NSUInteger to UI is anti-ergonomic in a language used to construct UI's. I'm also surprised that O stands for NSMutableDictionary but NSD for NSDict

Shortening NSUInteger to UI is anti-ergonomic in a language used to construct UI's. I'm also surprised that O stands for NSMutableDictionary but NSD for NSDictionary. What is an "O"? Another thing I would argue is that using the shorter #defines for mutables would encourage their use. Instead, it might be prudent to encourage use of the immutables.
