Show listing title when hover over map icon

Hi, in the business directory theme you click the map icon for a listing to open a pop up with a little info. That is fine but it would be handy to see the business name when you hover over the icon so you know what business it is before clicking. Does anyone know if it’s possible or if it’s an easy mod?

As an extension to this it would be good if free listings could have a different icon and be hovered over for the business name but not clickable for the pop up info box.

Any advice on this would be greatly appreciated.
