Does the Lua API offer a way to reflect the radar visibility range on the mini map? I'm not well versed on the modding API but if I can get a pointer I can submit a PR to add this feature to the mod. Great mod by the way!
After looking at the Wiki's page of the Radar prototype (https://wiki.factorio.com/Prototype/Radar), it seems there is no property to update the visibility range displayed on the mini map, maybe this should be automatically picked up by the base game instead.
