Hello @Ethix

Features are added using Widgets and they require to be placed into sidebars.

A solution would be to create a new sidebar and place it inside one of the Extra sections.

Then you could add the Feature Widgets into the newly created sidebar.

Again, this will require some customization of the theme files.

Here is the list of files you will need to edit,

/inc/widgets.php
/sections/extra1.php

Let me know if that helps.
