Hi everyone; I noticed that in cities with a lot of information in the map, I often would like to zoom deeper into the map than is possible in the standard interface, e.g. in Zürich at http://osm.org/go/0C0WCm2yw– … many small shops etc. with hard to read names. Is there an easy way? If not, then my humble suggestion is to increase the maximum zoom level of the map 
Technicaly this shouldn’t be a problem. We would need additional disk-space an CPU power to generate the tiles for an additional layer.
Just out of curiosity: Can anyone tell us, how many GByte mapnick currently uses for zoomlevel 19?
