Some developers like to add custom formatting to their module names to make it more visible on the module page. It may look nice, but this formatting breaks the sorting of the module list.
The Extension allows to display real module names, cleared of the custom html-formatting (icons, font size, font weight, color, etc). This helps you to keep order and clean on the modules page and sort the module list by truth name as it should be.
The extension doesn't affect the functionality of the modules and doesn't change its files. It fixes only the output of the module list and sets the correct sorting.
