[OpenLayers-Users] Removing features from a cluster

[Rob Hyx]

Thanks Xavier, I will take a look at that.

Another question about clustering: Can you continuously add features to a
clustered layer and have it re-cluster each time a new feature is added?
I'm having an issue where it's just replacing the previous feature with the
new one and I'm wondering if it's something I'm doing.

Thanks in advance!
