Caves (cave flora and fauna), villages (structures), trees (taller), tools

First for caves, I think adding more thrill would be a great thing. Like a rare unnamed hostile mob (3-4 blocks tall), that cannot be seen unless within 6 blocks from you (it camouflages), that causes torches or light to dim/flicker and other common hostile mobs to run away from it that causes them to ignore you. Second for caves is adding more fauna (other than bats) and flora, so caves could have some kind of life. Lush caves are great, but we need to have more life in common caves so it feels like the caves are alive. Third for villages, like making the common structures more expansive by a little bit, and also adding a new structure called a village municipal hall or building, that serves as a like a government for the village that could give you tasks or quests and reward you for it, and also holds hostile mobs such as pillagers etc. Fourth for trees, like making them 2 or 3 blocks taller Fifth for tools, I think expanding the cosmetic of armors to tools such as swords, bows, pickaxes, you name it, would be greatt
