How can we improve WHMCS?

It is requested to edit the Interacting with menus to support adding JavaScript code.

example:

use WHMCS\View\Menu\Item as MenuItem;

# 添加侧栏文档：https://docs.whmcs.com/Client_Area_Sidebars_Cheatsheet#Adding_an_Additional_Sidebar_Menu_Item
add_hook('ClientAreaPrimarySidebar', 1, function (MenuItem $primarySidebar)
{
if (!is_null($primarySidebar->getChild('My Domains Status Filter'))) {
$primarySidebar->getChild('My Domains Status Filter')
->addChild('Other Status')
->setLabel('Other Status')
->setUri("javascript:clickLeft('otherstatus')")
->setIcon('fa-globe')
->setOrder(50);
}
});
