Honestly, if they did an update or a pack that was to update (textures/models/UI/etc.) just for Gardening, Cooking (Baking) and Fishing—it be what we need. Which would better work with CoL, HCHSP and CKSP (and any pack that has food/dishes/plants/fish).
To upgrade Simple Living, add way more plants and dishes.
I mean I'd love it if they refreshed Cool Kitchen so much. If ice cream could come in a commercial display for businesses to scoop out for customers. If they had Mint Herb to make mint ice cream, etc.
I'd also like it if they finally put all "Baking Items" under Baking for the stove (and just if you don't have GTW you don't get the skill and extra recipes). I have lost my mind looking for recipes under the "wrong" selection. Like the L&D bake a cake (for cowplant). How stupid it feels to have to look up a guide to find out it is under "cooking" not "baking".....
It would also be nice if traits like vegetarian and lactose intolerant were under a new dietary panel/UI instead, with likes/dislikes of cuisine types, and bring back "Favourite Food"!
