The new feature adds another layer to the already-existing “save” option in Google Maps. Once you pinpoint a desired location, you can hit the “save” button to reveal a number of premade lists including “Want to Go,” “Starred,” and “Favorites.” Then you can choose the list you want the location to live in, or create a new list with a personalized title like “Vacation.” In Google Maps’ menu, you can find all your saved lists in the “Your Places” folder when you want to recall saved locations. Now each list will have a “share” button as well, which lets you grab its link to share with others or share it via different social networks. This should make it easier to share things like favorite restaurants and shopping locations with visiting out-of-town family and the like.
This is one of those features that most of us aren’t going to use very often, but when we need it, we really need it. If you’re after something similar for Apple Maps, I’ve been using Relay since it launched and I love it.
