It would be a great addition if you could add:
Magnetism
Changeable meshes (You can change object's meshes by loading a mesh then the object takes that form)
Coding Access- we can create codes that can change what objects do, e.g. we could make them follow a pathway if you had coding access (we could also do loads more),
And to be able to change what a object is made of. (Elements, e.g. you can do "74% Iron, 23% Hydrogen, 3% Oxygen" and objects have different reactions, depending on what elements they're made of.
