Short description of error
As known Blender uses the word "World" to define de 3D space to insert object in. My proposal is to change that name in "3D Space" or just "Space".
The word "World" in real life identifies a limited thing like a planet.
"Space" or "3D Space" instead is more general and intuitive.
Suppose for ex. an artist wants to draw a solar system or a planet. Drawing it into a "Space" is ok but drawing a Planet or a Solar system or a Galaxy etc into a "World" is kind of bizzarre.
Following that logic "gravity" property of the World IMHO has to be switched off by default as well: if a user needs it, the user will activate and set it at the proper value.
This logic IMHO will make Blender a little bit more consistent and coherent logic and intuitive to use.
