There are several plugins / extensions that customise the appearance infowindow (bubble) in a bit nicer way than what is possible with css, like extinfowindow, Elabel and Ebubble, of which the first one looks best to me.
It's easy to implement these extensions on a static html page with some standard Google maps code, but the gmap module adds a huge layer of complexity to implement it on Drupal.
So my question is what is the best way to add those kinds of plugins to the gmap module and have a nice infowindow on a Drupal site?
I have been checking out the gmap api, searching for issues or posts, but have not found any better way than hacking the gmap module js files. Is this really the only way, and if so, where to start?
