This one is sort of obvious, but the use case may not be.
Being able to align origins is a great way to alight objects.
But the hassle of editing the linked component (turning the visilbility on), saving it, pulling in the latest version, and then doing the same thing just to hide the origin again... that's a bit too much of a hassle 🙂
Could origin be treated as a compont so we can turn it on and off? (100% time grounded component that is)
Subidea: for many designs this would be equally useful functionality for bodies in no subcomponents.
Just allow hiding and making visible again. That's all.
