How can we improve WHMCS?

A simple request to implement product addon custom fields just as they are for normal products. The underpinnings of it are already present, even shown on invoices and containing validation fields, simply not exposed on order forms.

Also check the thread ( https://whmcs.community/topic/272513-product-addons-custom-fields-not-being-requested/page/2/ ) this was reported about having nearly 3000 views, being the top 3 link on Google regarding this matter so there is interest in completing this.
