Request to add an OSHA orange (#FF6600 or similar) circular background to the biohazard marker to improve visibility and match standard biohazard warning signage conventions. The current ( https://www.davnit.net/esmap/markers/biohazard.png ) easily gets (visually) lost on the map.
I put together a version with an OSHA orange background (like you'd see on actual biohazard warnings) that I think would be more visible. I attached an oversized image that you can use. Or, let me know what format / size and I'll be happy to convert it.
