I have just opened an enhancement issue for the marker layer - http://code.google.com/p/gmaps-api-issues/issues/detail?id=3266
The main object is to disable marker zooming when rendered within canvas elements. This is because, when zooming out, markers are overly enlarged giving an ugly user experience. The second object would be to be able to hide/show the marker layer via one method. This is particularly useful for those implementing clustering solutions. Feel free to add your support to this request. -- You received this message because you are subscribed to the Google Groups "Google Maps JavaScript API v3" group.
