I have been trying to change the size of the category icons. Am I correct that the procedure is to create

/XLite/modules/MyName/MyThemeName/View/Subcategories.php

which has the code

namespace XLite\Module\MyName\MyThemeName\View;

class Subcategories extends \XLite\View\Subcategories implements \XLite\Base\IDecorator
{
   
    protected function defineWidgetParams()
    {
        parent::defineWidgetParams();

        $this->widgetParams += array(
            self::PARAM_DISPLAY_MODE => new \XLite\Model\WidgetParam\Set(
                'Display mode', $this->getDisplayMode(), true, $this->displayModes
            ),
            self::PARAM_ICON_MAX_WIDTH => new \XLite\Model\WidgetParam\Int(
                'Maximal icon width', 200, true
            ),
            self::PARAM_ICON_MAX_HEIGHT => new \XLite\Model\WidgetParam\Int(
                'Maximal icon height', 200, true
            ),
        );
    }

}

to change icon size to 200px? It doesn't seem to work for me. Icons remain at 160px.
