@TrickyFoxy Great script—nicely done! Personally, I’d prefer a dedicated Chrome/Firefox extension. Setting up Tampermonkey can feel a bit hacky and requires extra steps (like manually enabling user scripts), and ViolentMonkey isn’t Manifest V3 compliant and installable at the moment. I think you’d reach a much wider audience—and get more feedback—with a proper extension.
(For context, I maintain the iD Strava Heatmap browser extension for Chrome and Firefox.)
