Complete customization of Island Sanctuaries, including building an inhabitable home and the return of all past seasonal event housing items to purchase in-game for a limited time. I really don't want my IS to have plot spaces only usable in pre-determined ways that make them all cookie-cutter, slightly differently customized, versions of themselves. Give me the ability to build an estate with a house and a f*$k ton of trees, ponds, and such if I want; or allow people to have their land fully-farmable if they so desire.
