Being able to select a whole group in the viewport would be nice.
You click on the group and it selects all the objects.


Xara has some practical examples of object organization, several kind are possible:

Groups: Cluster of objects like described above, possibility of nested groups.

Soft Groups: Stacking Objects can be spanned across several layers and reorganized afterward, does not change stacking order.

Named objects: Object or group of objects can be named and they can belong to several different names tags, making cross-association possible. An example here:

Live copies: Instancing.

There's also Clipview but that wouldn't apply much to 3d.


Ctrl+Clicking on a group will select an object inside a group, Ctrl+alt+Clicking will select nested groups inside, repeating will cycle through them...
