It has enabled us to set up a great map with multiple markers for our voluntary sector advice network.
Couldn't get the co-ordinates button to work in IE8, it just freezes and then goes to a blank screen after about 10 minutes, but switched to a different browser and that sorted that.
Feature request - it would be nice to be able to use the same marker in 2 different maps, e.g. an option to copy a marker and then you could assign the copy of the marker to a different map.
In summary superb extension. Thanks.
