currently we have an option to show the icon of the pinged item. it would be cool to also have an option to show the icon of the pinged entity. i would suggest to check whether or not xaeros map is installed, and then use the appropriate icons.

Xaero's Map is closed source and doesn't offer an API. It might still be possible to access the resources using reflection, but not sure if that can be a robust solution.

Besides using third-party resources, I have previously tried drawing the mobs texture, but I couldn't find an easy way to dynamically do this for all mob types (which should include modded entities).
