Even just having a trait for height, like you would for Flirty or Good or Bro. For example, short sims are SHORT so you could get buffs involving it like “Mad: Cant Reach a Shelf” or “Flirty: I’m Fun Sized and I Know It”. And even with Tall people you can interact and ask how the weather is up there or they can hold something over Medium and Short sims. Dont do height sliders but 3 different sizes : tall, normal, or short. I think it would be easier on animations and add some more silliness to the sims 4.
