Add new features to an existing web (MVP) working with Google Maps - 06/02/2017 04:04 EST

I need to add new features in my MVP: [login to view URL] As user I want to create a route in a Google Maps to show how was my last travel. For example I've traveled trought Japan and I visited Tokio, Kioto, etc... so I add to the map these points. One line is has to be drawed in order to connect the points, for example from Tokio to Kioto. Now the users just are able to have one map. To add this functionality this has to change in order to create different maps for one user. Viisit the web, undestand it and start to talk :)
