I finally added an option to find where objects are used:
While I was testing it with the cabinet (object 25), I was quite surprised by what it reported:
3 times in a single panel? That must be an error, I can’t recall any such thing. Let’s check the panel itself:
Yes, used three times there!
What about the telescope? Certainly just one occurrence?
Nope, three in the same location! I can now see the two spares at the bottom which I had never noticed either!
