On the Tesla navigation when I push the Flash I can see all charging stations. Superchargers red, all other grey. It would be nice when the different chargers (A: Tesla Destination Chargers and B: Already used chargers) are in different colors.
Currently it's a "feature" that as soon you shift from gear "P" to "D" or "R" that the Wifi disconnects. This make sense the the car switch to 3G/LTE GSM connection to avoid an interrupt of connectivity as soon driving out of the range of the Home Wifi.
