If you'd like that feature -- I would suggest Clexus:
www.mamboy.com
I use it. It's commercial, but a great component and well worth the $$$. Integration with CB is not perfect yet, but the author will release updated plugins for CB next week!
At first glance Clexus looks good. IMHO thier logo is hard to make out what it is and it's not for a "profesional" environment. Since it's not open source, can the Clexus logo be removed?
