Stable release: 3D rotation, 3D editor improvements & more.
I think he means the object wrapping / selection wrapping. Grouping some objects to a single one, and rotate the whole group.
By the way, is it possible the C3 Editor could remember all the selections or groups a user creates? For now the selection wrapping gets lost as soon as the user clicks away ...
Maybe if a selection wrapping is active, the user could dissolve it with another hit on the Enter key? Or something similar. It would help a lot.
