Is there a Plugin for CB called "CB Favorits"?

If not, this would be a New Development Request, which i badly miss at my site

What do this Plugin: A user can add other Users Profiles as Favorit, this can be integraded to the Edit/Connections/Messages/View Menu

and user can See all favorit added members by typical List Menu format

and other idea would be if a user make update can show the favorits menue the all user who made a profile update
