The plugin is nice, but it lacks this in my opinion:
You have an UI editor, but after I create a map it will not allow me to modify the map again. This is not very convenient.
It just displays the created map in shortcode and there is no way for me to later edit information etc. Also I do not even know where the plugin stores the data, is it on your server or mine?
If you could edit the plugin so people can later edit their maps it would improve the functionality by a great bit.
