  1. It would be nice to add ICE (In Case Of Emergency) entries (1 minimum, 3 desirable) to this. It would help Emergency Personnel contact your friends/relatives in case of an emergency.

    Also, it might be nice to tie in to MS HealthVault to show things like blood type, allergies etc.

    Great App. The suggestions are just to make it even better.
