Support for stable order clustering

[meesfrensel]

Hi, is there support for clustering in such a way that getLeaves returns the leaves in the same order as they appear in the source data? That is, a stable clustering?

Context: photos on a map where they were taken, clustered for usability. Clicking on a cluster, we'd like to show them ordered by date. Given that the data is just a list of IDs, and they were sorted before, it doesn't really make sense (for us) to query and re-sort them after getting the leaves of a cluster. Thanks.

Sorry for a late response. It's unfortunately inherent to the algorithms Supercluster is using (in particular, kd-tree-based spatial index). The only way to make the ordering stable is to sort it when returning, at which point it's easier to leave to the user side.
