Absolutely great mapping plugin. A fairly slight learning curve for basic usage (way gentler than others I’ve used) but still with strong flexibility under the hood. I also love that it includes both Open Cycle Map and Transit Map.
My only feature wish for it right now is the ability to make a color key to filter markers based on a vocabulary I create (eg. Cafes, Bars, Lodging, etc), but that by no means is straightforward to implement.
