I would like to suggest a list feature, versus reports. I'd like to print out a simplified list of physicians and their phone numbers and a simplified list of medications and dosage/administration instructions. The information on reports is not concise enough to carry around, not concise enough to hand to the doctor when you go to the office.
I would also like to be able to add dates that are not precise as some dates are only known in the month/year or just the year in the case of deceased relatives.
