I use OsmAnd for city navigation, and have copied some of the map points from karrot into OsmAnd manually, which is quite painful, I wonder if there is a neat way to either do an export from karrot, then import, or actually have the ability to live load them. I didn’t look into it much yet.
Then I wonder if other people would find this kind of feature useful? I mean the map inside karrot works, but it’s never going to have all the features of a dedicated map application.
OsmAnd has POIs, GPX files, overlay maps, OruxMaps probably has a bazillion things … at a guess adding GPX export from karrot might be the simplest and most viable option.
