 ### Main differences to https://github.com/ffnord/meshviewer
 #### Some features are maybe merged
 
+- Add modes - For example add a night layer and style
 - Updates selected node or list (incl. image stats cache-breaker) - not only overview tables
-- Zoom level for nodes (`nodeZoom`)
+- Zoom level if you click a node (`nodeZoom`) - Zoom level 22 available, bit it is to close for a click
 - Formatted Code
 - Grunt inline for some css and js - less requests
 - Icon font with only needed icons
