A further enhancement for me, would be the ability to print a monthly calendar of all birthdays, anniversaries, and other dates, with the choice of which types of events to display. Also being able to choose whether to print for living or deceased relatives would be desirable.
Features to the calendar print would also be the ability to add photos of each relative on the date of the birthday, or a collage of photos of all relatives with birthdays in a month, as a picture page of the calendar.
I second Tahir's suggestion. I would also like to have the possibility to at least export myheritage events in iCal format, so that I can add them to my regular calendaring programs. It would be even better if I was able to subscribe directly to my myheritage event calendar, so that any changes that are made in myheritage would automatically be updated in my other calendars.
