Would be fantastic if you could integrated in a near future an automatic function to call any WMS (Google Maps, but also OpenStreetMap, ...), like other solution can do today (Leafler, CARTO, Mapbox, ...).

Think could really improve your customers with that. Personally, Highcharts/Highmaps solution is for me one of the best API today, just missing that to be defo the best one... :)

Warm regards.
