Display inactive stations in a different colour on the map vs active stations

When I'm clicking on stations on the map to see how they are performing, many of them show no performance metrics and instead say "The station has not been active in the last 7 days".

I would like to have a visual indicator on the map to be able to distinguish these from the active stations without having to click on each one first.

If you want to go further, colour-coding the station hexes based on their performance would be the bees knees. For example see: https://heliumgeek.com/maps/iot-rewards-r8.html
