Yeah, you can just delete the old game folder and use the new one!
And that is a good idea :) i'll see what i can put together
also i dont know if this is something, but i played fullscreen for like an hour or so and the zooms in and out from plant to room gave me real bad motion sickness.
Edit: i think it could be partially fixed by having a Move Mode button or smthn. So you could click that and make everything moveable. It would make it a whole lot easier to organize plants and furniture without moving in and out constantly.
