You want to have a super administrator has limited permissions, limited components but current joomla Permssions can not do that. We provide a component to manage backend permissions very easily.

- Firstly, unzip package, install component and plugin.
- Go to administrator, Backend Access component.
- Select a user group or specific user you want to assign permissions.
- Tick on component or functions you dont want user or group could see.
