Hi Carlo, you might be interested in this discussion I started quite some time ago. I don’t have a great answer for you. I handle this by loading the KML, then manually iterating over the DataSource’s entities collection and updating the label properties on each. If you call entities.suspendEvents(), then iterate over entities.values, then call entities.resumeEvents(), performance isn’t too bad and you only have to do it once. Of course, if your KML comes from a NetworkLink, you have to watch for changes, which would be a great reason to get some more attention on the discussion I linked and push for a better solution from Cesium…
