This is so cool, Aerosys. I will 100% be buying this and the Sandbox Plugin soon once I'm ready to start setting up that part of my game. From testing in the demo, this is extremely intuitive and easy to use and works flawlessly! The only thing I can request down the road (if I may) is some ability to swap between variations or rotate the furniture items.
Visustella has a Furniture plugin that does this, but it requires their Events and Movements Core plugin which breaks some things with other plugins I use so I can't use it. They allow furniture items to have "variations" within the parent furniture item's notetags that links it to another furniture item. It's up to the developer how they utilize it. They can either make those variations different colors (blue bed, red bed, white bed, etc), or that same furniture item just rotated a different direction.
This will still be the one I buy regardless, but that feature would make it a no-brainer for anyone debating which furniture plugin to buy!
