"i have the gut feeling this is something amazing, but i dont
understand a damn thing..." lol, me too.
But I think this is a way to use "find in array" node to find arrays
inside arrays. If so this is very useful indeed. Thanks for sharing
one thing I noticed when recostructing the tree: when you reach at the
"find in array", be sure to first plug duplicates_array -> Array port,
THEN select in array -> Value, or else you may get context mismatch.
