Thank you the positive feedback. New ideas are always welcome.
You’re not the first one to request this feature. Unfortunately it’s not supported by Google Maps Iframe Embed API that my plugin is using. Google Maps JavaScript API supports custom markers and plugins using that API can easily provide this feature. The downside of the JavaScript API is that you need to obtain a Google API key to be able to use it.
Currently my plugin doesn’t support custom markers, but I will consider adding the feature in the future releases.
Best regards,
Petteri
