This. I find it incredibly ironic that the same people complaining that they have nothing to do in the game are often the same ones who scream bloody murder if there is even a hint new buildings are coming and they would need to redesign their layout. It has been highly implied in marketing/commentary since game launch that new vendors, and by extension, new buildings, might be in the cards. Those people might have lucked out with the Roost, but the island really does need more than the current five buildings plus houses, and there are plenty of people who would happily fit in new buildings into our layout.
In my island hopping, I have yet to come across an island, even the maxcore ones, that could not manage to fit in additional buildings. You don’t need a dozen picnic blanket scenes on one island!
