Is it possible to sort the categories and cities in alphabetical order or in order of more publications created? Finding a city between 20 or more is annoying

Will consider that.

That box shows only the main categories, but does not filter the users who are using the subcategories.

If the option to choose mother category is selected in Osclass, you will never be able to filter users, since users only have publications in the subcategories and not in the mother categories.

That box shows categories in those profiles are added, is not related to user items at all.
