composer.json file is sited):

• Leaflet Label: alternative tool tip hovers for polygons and line strings
• Leaflet Hash: bookmarking for maps, appends a hash of current map center and zoom to the URL, so you save and restore the "view port"
• Leaflet MarkerCluster: makes large marker populations easier to navigate through animated clustering and drill-down capability
• IP Geolocation Views & Maps: adds a swag of cool features such as centering options, markers colour-coded by any field in your View, cross-highlighting between content and map, geocoding and reverse geocoding options.
• Many more...
