I'd like to add a menu item to the admin block that will be available for managers.
I'm customizing an enrollment plugin, and it has a manage page, and the managers on the site have the necessary capabilities to access it and change enrollments. The plugin adds a "manage" menu item to the admin block. However that menu item is only available for users with the site:config capability.
Even if I change the plugin's settings.php file, the lib/pluginlib.php code only includes a plugin's settings.php if $hassiteconfig is true. This permission isn't given to managers by default. We're a small enough site and informal enough that I could grant managers that right, but my preference would be to add that item to the menu somehow for users with the enrol/manual:manage capability.
Is there another code path that can change the menu that would be less risky to customize?
