Click on a prop, and show what it’s been weld constainted with.
A drop down list would show “No-Collide” “Rope” (I don’t know why you would want it, but hey, you never know) “Axis” “Ballsocket”.
Lines would show up (you should be able to change the thickness of the line to a very thin to a semi-thick one) in green/red/blue whatever is good to see going from one prop to the one it’s been welded to.
So if I have welded 1 prop to 9 props, and I forgot what I welded, I could just check with that prop to see what it was welded to. Nine lines would go from that prop to the nine props.
