How can we improve WHMCS?

I have Marketgoo available for clients, but we also offer advanced managed SEO services, which many of our clients pay for, so I would like the ability to disable the client area Marketgoo display for those clients. It's just asking for trouble when one of our managed SEO clients see SEO services for $4.99 promoted in their client area when our managed services are a lot more for that. This feature should apply to all MarketConnect products, of course. Thanks for considering it!
