In progress higher density placenames
depending on zoomlevel, show much more placenames.
Isn't this a layering or categories question?
I'd like to have more such indicators as well. Names or symbols, such as "castle", "antenna" and the like.
But since a tablet has only limited space, it should be possible to filter these objects, depending on zoom level or so. Consider
- traffic (highways, roads, railways, street-categories)
- geography and/or surface (lakes, rivers, caves, forest coverage)
- population (cities by size/number of residents, administrative importance)
- places of interest (castles, tourist attractions, landmarks of various kinds)
and so on. A look at the current consumer-GPSes might help. My garmin eTrex and other models have quite an elaborate categorization of such objects (though Garmin did, as often, not make much of it). OSM is a great starting point as well.
