That looks like an interesting mod and the display cases look really nice.
For me however, I'm a bit of a purist and only want to use vanilla assets in my settlement builds, not because I'm a snob, but, because when I export my settlements using TransferSettlements, I want it to have no mod requirements other than the DLC's for anyone who wants to import it...also, because, for me, it's a challenge to create things using only the vanilla assets. As much of a "pain in the behind" it is to harvest Form ID's either through searching of forums, console commands or the Creation Kit(or xFOEdit), there is a feeling of satisfaction with achieving that pre-war something that isn't in the build menu.
