Whoohoo!!!! Cluster labels! So simple yet so satisfying - and super flexible to boot! This was really well thought out. Congrats to the MapViewer Beta Team.
I have one simple request. I don't like popups on my clusters. A default popup reads "This cluster represents n features" or something to that effect, which is fine I guess but if you're using clustering labels (and you should be), then the popup is redundant.
I don't want to speak for the entire communities needs but when I click on a labeled cluster, I don't intuitively expect to get a popup. What I expect to happen is for the map to zoom in on that cluster to the minimum extent necessary to break that cluster down one level.
So, it would be great if there could be a way to disable popups only on the cluster and instead trigger a zoom to extent action on it when clicked/tapped.
