Count of unread messages

I have a tab "messages" in our navigation menu and I was wondering of it is possible to add the number of unread messages.

So you get the tab "Messages 7"

And the number of unread messages bold or in another color for example.

Is that possible?

Hello

It can be done via custom modification in default PHP code. If you want I can do the mod for you but we need to discuss the details. Contact me via internal mail box if you are interested.  

How about something like this:
