Features that should be in Mcreator (And how they are seen in vanilla)

I understand some of these may not be possible, so I checked which of these could be seen in vanilla.

Living Entity:

Riding conditions (Pigs and striders do not let you ride them unless you put a saddle on them)

Movement control parameters (Horses do not let you control their movement unless they are wearing a saddle)

Flying Entity Condition (could be useful to make mobs that have both a landing and flying phase)

Climbing Entity with condition (Spiders can climb)

Multiple sounds for a category (Wolves have both passive and agressive idle sounds)

Sounds for when an entity attacks (Phantoms have a bite sound when they attack)

AI phases (Could be useful, wolves are somewhat similar to this, I don't know if this one is possible)

Inventory Open Requirements (Horses do not let you open their inventory unless tamed)

Different Taming foods from breeding, similar to how wolves are tamed with bones, but bred with meat.

Damage immunities revamp (changed to be similar to how multiple creative tabs works now, except you can select which specific damage types)

When entity hurts another one trigger (Could be useful to make mobs that deal poison to mobs they attack, like how cave spiders work)

Item/tool

Multiple Tool Types being used in one (Aside from multitool, which does the same thing, but give it some more builder control ie. just a pickaxe axe combination, or possibly a Pickaxe-Sword combination (Would be very useful for hammers)

Item having a disable shields and conditions for it.

Putting tool items into items (This would make it easier to make a sword that has a ranged attack or posibly a sword that could have a sword beam based on a certain item in its inventory.)

Item procedures for when an item is right clicked on an entity

Custom Armor Trims (although this is available with plugins, this would be a good feature in the base mod maker)

Biomes:

Updating biomes structure generation to put in structures based on a list similar to multiple creative tabs or repair items for tools (also including the more modern structures like ancient cities, trail ruins, and trial chambers would be good too.

Advancement:

One of the mod elements, which I don't think could see any changes that would be impactful, along with GUI and overlay

Fluid:

when entity is in fluid procedure, similar to how lava burns you when you are in it.

Block:

Change open bound GUI to have a condition logic parameter
