Dear Eleguan,
Thanks for your suggestion.
We have listed this in our plugin update list. We will try to do something for mobile in our future update of the plugin to make it more user friendly.
However, we unable to change our design for the desktop. Because the category can be more than 10, 20, or more, and based on your suggestion it will look destroyed and ugly if the category has more than 10, 20, or more. Also, we have a sorting option there.
Best Regards,
ThemeLooks Support Team
