Want to go on a Adventure with your Dog and don't want them to stray around hunting dangerous Squirrels? Command them to lie donw (they need to have learned the command of course) and they will lie down up to 300 min (default 5 min). Every Interaction with your Pet will Cancel the Command. Also it will fill up the Energy Motive.
I let unplayed Sims age up but there are some Sims i don't want to age up at all. You can use MCC to flag Sims one by one but i wanted to be able to add/remove a No Aging Trait easier. So i added a Pie Menu to Computer/Tablets where the No Aging Trait can be added/removed to Sims (mind. Age Toddler)
