The Pre Calendar, at least at this v1.1 OS point, is pretty lacking. I wish that the Universal Search would search though the calendar, or at least, and perhaps even better, I would like to see some search function incorporated into the Calendar.

As for pre-notifications of upcoming events, I'd like to see more than just 1 day, or less, for a less than full day event, and also the max notification on an all-day event is just 7 days.
