Max level to be applied by clicking a node or open a node. With value `18` near by buildings and streets should be visible.
Interesting if one of configured map provider has zoom-level under `18`.
## labelZoom (integer)
Min. level for node labels shown on the map. Labels aren't shown in first zoom levels and need performance.
## clientZoom (integer)
Min. level to set starting layer for client dots on map.
## nodeInfobox
