Integrates perfectly with WP 3.5.1.
Maps are fully "responsive" for mobile browsers. I'm using iThemes mobile-responsive "Builder" themes, work perfectly with this plugin.
Pages and posts load very quickly with this plugin as compared to other Google Map plugins.
Possible to place multiple unique markers on maps.
The free plugins that come with the Pro version are amazing - Gold version, Visitor-generated markers, Live-Chat plugin.
The whole plugin and the backend Settings has a great feel of professionalism and user-friendliness.
Other Google map plugins load up to 314 marker icons, whether you want them or not, causing my host to warn me of excessive files on my quota. With this plugin you only upload what you need.
I simply can't think of any improvements! Well done, guys!
