Can I manually insert this widget into my code by calling it with a function?
They say to do this, you find the function in /wp-includes/widgets.php, but AVH Extended Categories is not listed in this file; nor anything to do with categories.
When I use this Widget by adding it in /wp-admin/widgets.php, the rest of the code in my sidebar is not executed; hence I want to add it manually in my sidebar to test that the rest of my sidebar works too.
