Hi Markus!

It works. What I like to do is (using fakenames here) for example:
#list all subgroups of group=pca
g.list -sub group=pca

# or maybe
g.list type=subgroup group=pca


# output is a dozzen of subgroups, let's say:
pca_all
pca_half
pca_a
pca_b
pca_c
[...]

# then remove one of them
g.remove group=pca subgroup=pca_b

I imagine something like this. Wouldn't it be useful?
