My feelings about Island Living and a huge request to the developers

Actually, I think Island Living is great. I LOVE Sulani (I think I will never leave the island again) the objects and plants are just beautiful and also the jobs are very interesting (except that it´s sad that the lifeguard career is not active). Unlike many others, it doesn´t bother me that we don´t have scuba diving. But there is something else that REALLY bothers me, and I hope that the developers can bring that into the game with a patch. Iseland Living is perfect for single sims in terms of its activities. But what about my couples? They can not play together in the water. They can not build sandcastles together. These animations are already present in the game. Sims can build a snowman together, so why not sandcastles as well? And as for playing in the water, there is the animation from the "romantic garden stuff"pack. Sims can play together in the big fountain. This animation (see pictures) could have been perfect for the ocean.
And then I think I'll never understand why only one Sim can sit in a sailboat. It would be so romantic as a couple to sail in the sunset. :'(
I had a date with my couple on the beach today, but I realized that I didn´t know what to do with them there. There are simply no activities for couples, just for single sims. And as a player who plays more with couples than with singles, that's sad.
Furthermore, a few group activities such as volleyball or badminton would have been perfect for the beach. And why can´t sims talk with each other when they lie on the lounge chairs?
If the pack had more activities for couples / groups, it would be the perfect pack. I do not regret the purchase, but I would like to see improvements in a future patch. Please make the beautiful island more couple friendly.
