In Potlatch it is possible to add POIs in edit mode that aren’t visible when you are in view mode. Is there a way of viewing and printing OSM maps with all POIs displayed? It’s very annoying when you go to the trouble of adding in points only to find they aren’t displayed anyway.
http://www.lenz-online.de/osm/ select the POIs you want to display and they magically appear on the map 
This is great! Just what’s needed.
