Being able to get closer with villagers! Like inviting multiple to your house, asking them favors which they may or may not do for you, initiating games with them, going shopping together, fun stuff.
diving competitions would be nice. maybe even gold and silver wetsuits!
also, i really wish i could open my inventory when sitting down.
Yes yes yes, I WISH we could choose where villagers plot their homes. I mean I get that we're not some kind of dictator mayor but it's so annoying when they plot right on a path. I wish we could choose how colored the lights are. I like the stained glass lamps but I'm not super fond of the wash of purple it produces, especially when you have more than one lamp.
Get the furniture that's inside the dream suite building... "oh no that's incense and druggie decorations kids shouldn't have that" lmfao they already have the burner and sticks so lol
