My ideas for MCreator

I don't know how to use GitHub so I'm asking you to share my ideas for new features for MCreator.
At first the simplest.
New block

<[Get Player Nickname]

<[is entity in flight]

<[Is entity aggressive]

For example a zombie that goes to hit a player will be considered aggressive and a cow will not
My next idea is new features for tamed animals.
Please add for them the ability to chase the owner in flight and the ability for players to fly on this animal, as well as a combination of movement on the ground and in the air. (Like on dragons from some modifications)
And the latter, in my opinion, is the most difficult. Changing mob models and textures using procedures.
New blocks:
Get provided entity model / texture.
[model / texture]
Change model / texture to [Optional]
Return the main model / texture
And so on...

If you do not understand something due to incorrect translation, ask me.
