Anyone else here on /r/travel think it would be a nice idea to have the option to save and share your current & past itineraries? Personally, as someone who has never traveled abroad before, I find it might be useful to look at other travelers' routes to get a better idea of where I might want to go and how to go about doing it. For instance, going from London > Amsterdamn > Florence for a smoother transition than London > Florence > Amsterdam; etc.
Edit: Also, to see the total cost of their trip to give an estimate of what it may cost another person to follow that same itinerary.
