Ability to exclude super admins from approvals / remove approver status from super admins

Thank you for bringing this up, @Karsten. This is an important improvement. Things that can happen, do happen: Once, a super admin has - unintentionally - not only approved but also sent out one of my customer e-mails at a wrong time and to the wrong list. That was a shocking moment for me when I realised it and irritated the customers.
