   2 Things to do:
   3 ¥ Make preferences window pretty
   4 ¥ Hot Keys
   5     - hot keys can't be set when NSBGOnly is on. The window is not key,
   6       so the KeyBroadcaster does not pick up key combos
   7     - going to need a different way of defining key combos
   8 ¥ Optimize
   9 ¥ Apple Events! Apple Events! Apple Events!
