There’s subcategories for teleporter items and NPCs/IO stuff that are in the Toys/Interactive category of the condo inventory, but I think they’d fit better in the Building category. I tend to use teleporters in a lot of my builds, and IO will especially be very useful for building games/interactable objects/etc.
I mean, they are interactive items, so I don’t really see the issue. Yes, you can use them in builds but they aren’t building materials themselves, though.
