Just a little thing...
When 2 objects (in the same group with or not the same type) have the same name only one object appears in the list of the group!
Does it make sens to permit or forbid this? ( put something like 2 cube or never same name ...)
Permit seems very cool!
Say you have a group a 100 cubes (each cube is named box) maybe 100 box will be cool to have in the vertical list ?
Useful when you copy something for example! ;)
You are directly informed that there are 24 glasses named crystal on the table! ;)
