Taste of Tylo contains many QoL/UX/UI Mods, as well as some small item/mob/block additions. There are also some performance improving mods.
This modpack was made keeping the vanilla experience in focus, while upgrading many UX issues I find with base MC.
Major mod additions include backpacks, new dungeon structures, and new inventory interactions.
I also recommend adding in VanillaTweaks
They have some great data packs that follow the theme of this modpack, and are downloadable separately from each other, allowing for a personalized experience.
