With Concrete5 you can decide either you enable or disable some CK-Editor plugins to the users of your website.
With the Advanced Editor Permissions under System & Settings you can now choose which groups are allowed to use certain Plugins.
For example if you want to enable "Source Code" plugin for administrators only:
/dashboard/system/basics/advanced_editor
Note: This Addon does not interfer with CK-Editor Pluginator Addon as it has its own permissions so you can use both Addons
