Feature Request: Give Admins Ability to Change Agent Status

My agents keep forgetting to change their Zopim status to away or invisible.  They walk away from their computer, and occasionally we end up with a ton of chat requests that don't get handled.  It is making me crazy.

Could we give admin accounts the ability to go into the list of agents and be able to change an agents status?  Even just the ability to log them out would be enough...
