The first thing I thought of when reading that tweet was the Create a Style ability we had in Sims 3. I am probably way wrong, but that is what my mind immediately went to.
Although, if I'm being honest, it's something I used to miss and want greatly in Sims 4, but having not had it for so long, I don't really long for it anymore. It bugged my game so much, especially when the option to save the specific style you created came about. My game was already so laggy, but with the addition of over-saving styles I'd created, it just overwhelmed my game.
