This extension is changing the display of the list of categories in the backend so it is much easier to visualise the categories to add or edit.
This quality of life's extension is removing the pagination and introduce an accordion over the main categories thus it does hide sub categories unless the user is clicking to see the list of subcategories belonging to a particular main category. See the screenshot for detail.

This extension is working with Vqmod and Tpl/Twig.

This code cannot be resold once purchased unless I give the consent.
