What’s a gameplay feature you’ve NEVER used? New ideas to spice up your game!

Things I have never done:

-Conservation activities from Island Living
-Lifeguard job from Island Living
-Robots from Discover University (not really had time for that yet!) Same with a lot of other stuff from DU.
-Defeated the Mother. I came very close once but the sim I was focusing on died and I abandoned that save afterwards
-Made Ambrosia
-Resurrected a sim without cheating
-Used the jewel crown
-Completed the Potion aspiration from ROM

Some barely used things:
-I'm not sure I've ever used the Money Tree in Sims 4. Either I don't have the points for it or I have filtered to traits or potions and it doesn't show up. I also keep forgetting it exists!
-I've barely used the odd jobs from Island Living and lived in a house with the volcano trait maybe once
-I'm not sure if I have had a plantsim in Sims 4. I can't picture what they look like this time round so maybe not.

@Prink34320, I LOVE the Family Bulletin Board and use it in almost every household with children or teens.
