Is there a significant difference between your mod and the Ghost Scanner 2 mod which is a refactored version of Ghost Scanner from Optera?

Yes, two things:
1. This mod only displays missing construction materials, so ghost which can be built are ignored. Ghost Scanner (2) show all ghosts in the network, even if the items are available.
2. Performance. On my base Ghost Scanner 2 caused major lag spikes when placed in large logistic networks. This should not be the case with this mod, which is why I wrote it in the first place.

Thanks for the reply. I play mainly on the SE+K2 build, so I'll test it on my last save as soon as I have time.

If you have any issues, please let me know. It is written and tested with Space Exploration, but you never know.
