Hi Pilou, well all the details have yet to be determined, but likely one big difference will be that Groups will allow for a hierarchy, like names that are a child of other names and can be expanded or collapsed.

So the idea there is that it will be easier to manage a linked set of names with Groups since you will be able to go to the parent item in the scene browser and use the various controls (hide/lock/select) to work on all those items at once.
