The Map tools - Map Regions & Map Counties are very useful. However having mapped various countries I am thinking it would be useful to have one level above the Map Regions. That of Map Countries.
The idea would be to have each country shaded green or red as per the previous maps but on a COUNTRY by country basis. The selector could be continents so North America/South America/Europe/Asia/Africa/Oceania/Antartica then the map would show say all of Europe and shade in red or green according to whether the country had been cached in.
The beauty of this sort of report is that the data already exists in the database and the outline polygons for the maps already exist. Particularly for Europe with its little pockets of countries and territories this would be a useful report. So it wouldn't take much to add this feature,
It could even be used as a teaser report for showing what paying members get in more detail with map regions and map counties encouraging further subscriptions.
