Please add moderator features

Dear sir, i am asking you please to add the moderator features that no one allow to delete any member from the group except the creator of the group and the creator of the group is the only one who can assign any other member of the group to be admin in the group where he or she can allow to add new members in the group or delete someone from the group.gentlemen am using your app in daily basis and am really having hard time managing the group call because of this issue so many times that my group has been deleted by someone else and so many time members been deleted from someone else because of someone else please please please add these features

Am having high faith on you and feeling that you will add these features in the next update

Many thanks
