Family subfolders are very nice. Is any chance this might be a step towards Family inheritance? I.e. subfamiles -- e.g. enemy > bug > bee, enemy > bug > wasp, enemy > barbarian > chief, etc etc? I know this can technically be done currently, just very flat, but it would be great if the subfolders could optionally be treated as Families themselves.
Basically, this would mean that if I made a Queen Bumble Bee a member of the Bee Family, that it would automatically also be an enemy and a bug. Currently, I believe that you must specify that this object is a member of all three Families individually.
Visually, this could mean just adding subfolders "into" instead of just "around" the Families.
