Module
The module shows the same links in a module position, with its own scope and order.
Create it from Content > Site Modules > New > Easy Article Navigation. It only renders on a single article page. On a category blog or a home page it stays empty.
The module does not follow the plugin's insert setting. Give the module its own layout, labels, scope, order, series fields, and colors. Use that when one menu should use cards and another should use a stacked sidebar.
If both the plugin insert and the module are on, the visitor sees two blocks. Turn insert off when the module is the one you want.
Module cache is off in the module form. After you change an article, clear the Joomla cache if the site cache is enabled. The plugin also clears its own cache group when an article is saved.
