What functions do we need to make more RPG like mods.

Hello everyone.

I know that some of the things what i'm going to write are requested yet but i just want to collect some of them to help the developers to improve MCreator.

-Custom Vanilla GUI editor (Editing the main inventory of the player adding some custom slots for items and make the items custom bindings to the slot ID's for example: jeweleries)
-The items for custom GUI's can have their own models like rings or necklaces
-Unbreakable tool option in the tool creation
-Custom ranged weapon ammunition with potion effects, icons and models
-Let the ranged weapons use multiple ammunitions (In the ranged weapon creation there could be a list where we can add what kind of ammunitions can use)
-Adding custom particles and potion effects with icons and textures
-Adding custom pets and make a better solution for rideable mobs (A basic AI for rideable mobs and custom models)
-Creating shield items with custom textures and functions or even models
-Custom armour models
-Let the items keep their icons even if they have a 3D model
-Adding custom fishing eqipement
-Adding capes

I think with these elements we can make much better mods and i hope you guys will support my idea and the other people who wrote the same :)
