MCCommand Center is definitely great and I love having it running in my game.
Another one I really like is the
UI Extensions Cheat Mod. It has a lot of really helpful things it can do and it's really easy to use. You can use it to drag needs a little bit or fill and deplete them completely, get rid of moodlets, easily add or subtract money from family funds, it also allows you to see the actual relationship value for both friendship and romance by clicking on the sim in your relationship panel and can increase or decrease both as needed. I get a LOT of use out of this mod.
