iOS9 isn't even out, and I already have some idea of what I'd like to see in a future update:
-Ability to add location of a parking lot to a Calendar event. I have an event set up for my Sunday meetings, and the location is in the event. However, due to an increase in the size of my congregation, I will likely have to park elsewhere. There's another church building, at which I parked last week. I'd like to program its address into the event and have Calendar factor in the time it takes to drive to that building and to walk to my building into the total travel time.
