I have been using the editor on my project recently and well I hate it. I know that seems harsh but seriously its like the BeamNG teams disowned child that they kicked out of the house. I can say that yes it does work and it gets the job done... buttttttt seeing how much the team has grown and how big the modding community is getting I think it is about time they re- create the editor.
Well the nodebeam editor wasn't actually created by the BeamNG team, so it's not their job to update it.
