Hi, I also migrated. And got a new hobby.
I have a problem with the import process. For many years, I did upload my pictures to Panoramio using a camera WITHOUT gps and compas, and added gps manually. During the import within Mapillary all these pictures have received a compass heading North, 0 degrees, but it should be NULL or 'unknown' or something. Is it possible to remove a wrong heading of 0 in case it was just unkown? Because It is too much work to correct 1000s pictures compas heading manually..
And apart from the missing features-list as indicated by manuschwendener, I do miss the possibility to move the gps coordinates easilly up to 20 meters or so.
