how do you take a node (i know how to do that you just hold a node on the vehicle and drag) and have it in one place in the air/attach the node to a vehicle node? Is this possible?
We currently only have 2 active developers. There's stil lots of major bugs to fix, adding features is not a priority.
But you're more than welcome to implement it yourself: https://github.com/RigsOfRods/rigs-of-rods/
