Hey @Mike van der Valk4, we're actually working on improving the group moderator/admin's ability.
The moderators and admins will be able to delete/edit their groups content. The admins will have extra ability to see the analytics of their group as well as editing the name, profile picture, etc. of the group. They'll also be able to change the role of other members.
One more change will be the permission to invite members to a group. We will let admin pick the permission level around who can invite new members. It can be members, moderators, or admins.
