Yes to all of this! I am such a hopeless romantic and I would love a Romance GP to develop the romance system with chemistry, turn ons/offs, and more interactions. I really miss my sim couples cuddling in bed and dancing together and I would love to see them holding hands, jumping in each other's arms, showering together etc. I think it would be cute if child/teen sims could develop crushes too. I want a loyal trait and my soulmates to always be faithful to each other. I would also love to see weddings developed e.g. with ask parent/guardian for permission to marry, table proposals, hen/stag parties, wedding traditions, bouquets, veils, rings, funny speeches, a first dance, honeymoons, carry over the threshold etc. Picnics and an Italian themed world would be perfect too and perhaps we could have a new musical instrument like the harp or the lute.
