For your last request (about the maps), it is available to paying members through Map Regions/Map Counties tools (in the Tools menu). I know these requests are about integrating into the stats, but I thought I should point out that these tools exist.
For your specific example, you could use Map Counties and specify Sweden, then look for the red county and click on it. It will show (for example) "0 finds in Arjeplog" as a link. Clicking on that link will give a map of all available caches in that county.
