What would you change/tweak in Sims 4?

As for Gameplay I'd

• Add More Weather Types
  • Fog - Especially in Hensford, Moonwood Mill & Forgotten Hollow
  • Hail
  • Dust Storms - Horse Ranch
  • Sandstorms - Deserts only
• Do some finishing touches on the Vampires pack
  • Add a Cemetery if you have Life & Death to the neighborhood
  • Give Vampires & Werewolves a Silver Aversion perhaps even an additional weakness
  • Horses specifically All White Horses will sense a Vampire and be unnerved - Lore Accurate
  • All black horse will sense a Vampire but not really mind them - My own invention
  • Bring Back Eclipsing Fog from Sims 3 as a Master Vampire Power 
  • Bring back the hunting technique they had in Sims 3 where they try to look for the best Sim for plasma 
  • If you have Spooky Stuff pack it will unlock a Bela Lugosi Dracula and Maila Nurmi Vampira costume 
  • Vain Vampires will get the "Dead But Delicious" moodlet (What we Do in the Shadows movie Reference)
  • All Vampire can use the "Dark Greetings" when they meet up with each other (WWDS TV show Reference)
•  CAS Updates
  • I'd split up Rain Gear & Cold Weather Clothing
  • I'd add a Costume Tab 
    • Add more costumes
      • Classic Monsters & Commonly seen ones
        • Dracula
        • Det. Sherlock Holmes
• CAP Update 
  • Yellow Life Jacket Vest
  • Add Costumes Tab
  • Update knitting to be able to make sweaters for Cats & Dogs  
  • Career Clothing & Equipment Tab
  • Holiday Themed Collars & Tags
• Careers - Since the question pertains to things we already have 
  • Archaeology - We have the skill but no career. Branches would be different types or zones of research
    • Examples:
      • Archaeology of the Americas - This would cover the current zone in South America
      • Classical - Greek & Roman 
      • Egyptology - Egypt of course
      • Maritime - Shipping, Military and covers Underwater Archaeology, which itself brings back Scuba Diving 
      • Medieval - European Countries & Great Britain 
      • Mesopotamian - Areas within the fertile Crescent 
      • Sinology - China 
      • Viking - Scandinavian Zones
    • Gives us more areas to work with and more interesting artifacts in any zone they make
    • They could also do this as apart of a Museum pack which has been asked for in the past to improve this lot. Although more folks wanted diversified types like 
      • Archaeological 
      • Art Museum
      • Maritime 
      • Natural History
      • science & Technology
  • Fortune Teller - They have been giving us bits an pieces of this career from Sims 3 they might as well finish up
  • Private Detective - Just a diversification of the Detective Career we already have 
  • Veterinarian - Again another area where the career was simply a Skill. This could be an area of significant improvement 
• Baking - If I had my way I'd put that in the Base Game
  • First I'd rework all the recipes in Cooking, Baking & Gourmet Cooking and place them in more appropriate and easier to guess categories. 
  • I'd specifically do away with the generic "Fruit Pie"  in favor of Raspberry Pie or Huckleberry Pie etc. And give each a slightly different crust variation to show them off differently
  • Secondly I'd recompense Get to Work Simmers for the change by adding Perfumery & Soap Making as a Skill
    • Add Bakery as a new lot type
    • Add Perfumery as a new Retail Lot
      • With new stylish cabinetry and store items to effectively display these items
      • Perfumes would be made with any current Florals & Botanicals and add any that would make sense for what we are trying to do. For example Lavender or Orange Tree for Orange Blossoms water. It would be updated as needed with new packs. 
      • You customize the bottle shape & color as well as the formula for the perfumes.
      • If Glassblowing is ever introduced then shazzam new bottles designs for an update
      • In game it would be shown as a small glass bottle in whatever shape and color perhaps shown off at the makeup table or on a small mirrored tray
      • For soap you customize the formula and the color of the soap. Maybe even packaging
