I'm all for wishlists, truly...
I appreciate the desire to just info dump a wishlist for new housing features, but it seems extremely likely that housing options will come into play for Island Sanctuary. That said, to implement something like this would be a HUGE undertaking and the team is only so large. Give them time, I'm sure they're working on it.
But yeah, since we're doing wishlists, I think Island Sanctuary housing should just be simple and people should understand what they're getting, which is a limited, more constrained housing option, should one come around. It's already subtly implied that this is going to be considered and the idea of simple housing that requires cowries and workshop crafting (instead of player crafting or MB purchases) should be treated as a best case scenario.
Anything else, like themes (don't forget this is an island) and additional social features might be a bridge too far. Also, there is no bridge back to Moraby so clearly you gotta make use of what's on the island and that might mean coconut dinnerware and palm frond carpets for the overwhelming majority of folks.
