I look forward to Version 1.0. Input minimal identification information. Update everyone's list with beaming support. Mark ToDo items as they are completed. The chronological approach.
Information is recorded as discrete events.
Each event may be a Problems, Meds, Labs, Consults, etc. The type of event and its' status is represented via some cool icons on a summary page for each patient. Information can be shared via beaming. The information is laid out in a logical manner. Navigating between patients is easy.
