Need to update end points

Useful last week. Good routing options. We had some difficulty because the direction (end point) in this app sometimes different than the metro/train signage. Eg, the north end of line 12. Is it Porte de la Chapelle or Front Populaire (new station?)? Saw both. Resolved by checking the map in the station. See ratp.fr for the updated map.
