On the subject of definitions, I wish I could set up OS X's 3-finger tap dictionary lookup to give me definitions in other languages. It would be one of the most useful things ever for learning another language. I could start trying to read French or German and triple tap a word and have it give me the translation to English and the dictionary definition in German (which would pop up a window where you could three finger tap again for a word in the definition that you don't yet know)
