Uploading a new version today that is simpler.
The addon is renamed
FilterWorldMap and you can turn filters on/off using the menu in the top-right corner of the World Map.

I have not yet changed it to pick specific kinds of POIs to filter -- I wanted to get this improvement done first so that the options are easier to manage should I proceed to add any more.
