I think for the moment it is on the back burner as the Team bring the Beta side in to Stable. However if you follow Heather’s brief and concise tutorial you can implement Leaflet in to your application quite easily. Heather’s code is commented so BE SURE to read them (I missed one and looped around for a while scratching my head but if I had been more observant it would have only taken twenty minutes or less to get it all up and running).
