I am not sure if this is what he's talking about, but I wouldn't mind having the ability to group a selection of objects (sprites, mostly) and assign a "group" to them. For instance a tree with a trunk, canopy, and apples could be 3 seperate sprite objects, with different properties/behaviors. trunk is a plain sprite, canopy is a solid to platform on, and apples can fall to the ground. To do this now you would have to select each object (either with a marquee selection or by clicking each). If it were possible to make a "group" of objects, such as in illustrator or flash, you can more easily select and duplicate/reposition a series of objects. Families to me are more for event sheet work, where as group would be a for the layout view and would make multiple objects selectable by one click.
