Players can modify nearly every aspect of a Sim's body in Sims 4, except one: height. Sims can even go on blind dates or choose to have a one night stand rather than needing to flirt and enter a romantic relationship with another Sim in order to WooHoo. In the same vein as food delivery, littlemssam's SimDa Dating App mod allows Sims the chance for better online dating. Players can add another one of littlemssam's mods to customize the number of servings if they would prefer. This works on the same system as the pizza delivery service, and players can order a single, family, or party serving. With the LittleMsSam's Food Delivery Service App mod by littlemssam, Sims can now order any food that's available in the game for delivery. In the age of take-out apps like GrubHub and Postmates, players may want their Sims to experience similar luxuries. For example, right-clicking the Sim's career will allow the player to promote them, and right-clicking Household Funds will allow the player to set the amount of money their Sims have. Rather than needing to open the console, with UI Cheats Extension, players can simply right-click the User Interface to cheat. The UI Cheats Extension by weerbesu makes cheating user-friendly and part of the game. Using the MC Population Controls, they can choose for Sims saved to a player's Gallery to spawn in the world in place of the randomly-generated Sim characters. Most importantly, players can now populate the world of The Sims 4 with their custom Sims, rather than random townies.

Players can increase their maximum household size to up to 140 Sims, set skill difficulty, and set how many in-game days a Sim will stay a certain age. Sims can now pay child support, adjust their bills, and have a risky WooHoo that might result in an unplanned pregnancy. There is an auto-saving option so players never lose too much of their game if there is a freeze or crash. The MC Command Center (and MC WooHoo) were developed by deaderpool and allow players more freedom within the game.
