Also, ability to view the level of our Pokémon without other apps.
And a little more friend history info, like
- what their previous names were (to identify after somebody changes their game name), and
- a date when we became friends (to help decide which friends to drop when clearing space on our list for new friends). [of course, neither of those is really necessary if we actually know our friends enough to have a way to communicate with them outside of the game…]
