Would you like to have more trait slots for your Sim?

I'd like an additional trait for toddlers and kids, and more traits in general. With adults, I'm more likely to run out of traits that fit my Sim than I am to run out of trait slots.

It would also be nice to have the ability to change at least one trait as Sims become adults (from YA) and elders. An ambitious Sim might become more family-oriented, for example.
