Suggestions for when the 1.16 version comes

Village Creator: allows you to add custom villages you can select what build the village has so it could look like the plains ones or the desert ones and allow people to select what blocks the buildings and path are and choose what spawns in them like villagers and cats for normal villages and choose what biome and dimension they spawn in

Hitbox Image: shows a square next to a player it can change the size and shows you how big your mob's hitbox is

More (Number Of X's Here) like the blue fire course plants add back the dead bushes per chunk (if it's still there I can't find it)

Option to make a custom tree outside of the biome option: you can choose I will make an example so I choose it to look like a tall jungle tree a replace the wood with spruce and the leaves with blue wool the vines are the same and there now I select the surface and whatever biome I want and it will spawn there with the frequency that I chose then you can select a plant object to be the sapling and what you click on it with to grow it

Option to make a plant able to be put into a flower pot will not work with plants that can stack 

Option to make a mob climb walls like the spider in Minecraft

Gravity: allows you to choose how high you jump in a dimension and 5 would be default 10 you'd be like the moon 1 would be like Jupiter 

Option to add oak spruce jungle dark oak birch or acacia tree into biomes you could even select two

that's all i have please let me know if you guys could do these
