Geirhog, there was a discussion of this a bit over a year ago at https://xnau.com/product_support/locations-map/comment-page-1/#comments

I am very interested in this plugin & what it can do.
I would like to use this for airports, how will it show if I have more than one marker at the exact same location?
Other programs I have seen combine them into one marker with the number of icons.

This is an interesting question. I had not considered how to handle multiple markers in the same location. As it is, it will just stack them on top of each other, but that could be changed.

Could you point me in the direction to learn how to make this happen?

Looks like it’s possible, but requires a pretty deep dive into the code. Check out this response at Stack Overflow There may be some more discussions on the subject there as well.
