and, first of all, let me thank you for such an interesting plugin.
We're considering to use for a map-based project, but we've come to several technical questions.
1. We'll be having relatively many markers on our map - hundreds of them constantly (max. ~3000 expected). That would, no doubt, require marker clusterization.
If Leaflet uses client-side clustering, it won't be enough. So, is server clusterization supported?
2. How do markers queried before passing them to the map? Is it current viewport-based query, or all of the markers selected without considering their coordinates?
3. Is clustering available only for Pro-version?
Thank you in advance.
