very nice plugin. would even spend money on it. good work. it just seems that the zoneIndicatorStrength is not displayed on customer maps?

Thanks!
It should work on procedural and custom maps. Have you tested it? Max value is 50 and min value 1.

is it only show inside the world or on the map? suggestion: would be grat if you can see the zones on the map like a circle :)

Yes it only shows in the real world. I will maybe add something to the world map if its possible.
