Is there any chance that you could add the icon on map instead of grid or coordinates? Thank you

It gets very tricky trying to add personal map markers. This plugin is more aimed towards reminding players where they died in case they die when trying to run back to their body and forget where they were going.
Sorry, I've yet to see a good solution to what you are proposing.

I undestand. Thank you very much for the response and for your work.
