During route planning usually I switch on Kurviger passes and OSM passes Kurviger passes gi e more info, but some OSM passes are not in Kurviger passes..
This frequently leads to clustering of passes although there is only one pass, but that pass is in OSM passes and in Kurviger passes. Example route belonging to screenshot above:
Usually the Kurviger pass contains much more information, and clustering leads to the need for zooming to add pass to the route, so I propose: If Kurviger passes and OSM passes are enabled, do not show icons for OSM passes, which contain the same pass as a shown Kurviger pass.
