It occurred to me when I was toying with trying to build a "house" on my island, that I'd be able to actually build something pretty fantastic if I could only place indoor items on the island in addition to the outdoor items.
Using partitions, pillars, and lofts, we could conceivably build actual houses on the island! So how's about it SE? Why not let us place both indoor and outdoor items on the island and bump the item count to 400!
