It would be great to possible set permissions to set visibility also for other users/groups. http://octobercms.com/docs/plugin/registration#navigation-permissions

yes, please, upgrade it this way...

You can add: public function registerPermissions() { return [ 'raviraj.rjgallery.*' => ['label' => 'Access Gallery Plugin'], ]; } to the plugin.php file to allow you to restrict access using the admin panel.

Try add to the plugin.php: public function registerPermissions() { return [ 'raviraj.rjgallery.*' => ['label' => 'Access Gallery Plugin', 'tab' => 'RJ Gallery'] ]; }
