Andrew's pose player and teleport mod, along with various pose packs. The pose player gives you 2 options when clicking a sim - Pose by pack and by name. The teleport mod gives you a cc piece, which is a pure white knight statue that you can use to teleport a sim somewhere. If you have pose packs you will need to put the knights somewhere (usually having it overlap others for multiple sims and/or placing it in an object) Its hard to explain but i'm sure there is a tutorial somewhere.
UI extension cheats - Gives you various cheats for the UI, like right clicking funds to modify them, right clicking the clock to set time, clicking on needs to fill them, right clicking a sim in relationships to modify their relationships, ect. I Will share links as soon as i find them.
