Area-Links-List or Anchor-Links for Countries

Hi, 
thanks for this great plugin!

Instead a list of posts by area I would suggest a simple list of areas linked 
to the index.php - like terms. For better overview, as the post list is simply 
to long. 

If this is to complicated, I would suggest anchors by country - so I could link 
the different areas. 
To give you an example: http://berufebilder.de/karte/#ca

I did it manually, but its to complicated as the list changes allways. Trying 
to put anchors in the following code, I didn't get managed. 

Can anybody help me?

It has to be something like: $country_heading = '<h3 id="country_name">' . 
$country_name . '</h3>';

Thanks for your help! 
See below the full code.
