Find a destination within current route
It would be nice to be able to find a destination within your current route without cancelling your current trip. Example: You are driving from Orlando to Tampa, and halfway there you decide you want some coffee. Currently you have to cancel your trip to search and then once you get coffee, search for your original destination. But imagine if you could just do a search for coffee while you're on your trip, add that as a pit stop, and then continue on your way.
