Queries reg two plugins

We are using wordpress 3.8.5

We are using wp post navigation (https://wordpress.org/plugins/wp-post-navigation/) plugin for navigating Prev / Next posts. If a post is included in more than one category this is not working

We are using Ideal Interactive Maps for displaying locations (https://wordpress.org/plugins/ideal-interactive-map/). The locations are displayed as dots. When we hover the country name is getting displayed. Instead could we have the option to display the country names near the added locations (dots) by default.
