Great! Thank you for this tool.
I was wondering if it would be possible to edit the minimum and maximum zoom-level in the map file as well. I find that secondary roads disappear a little bit too early when zooming out. I have already tried to edit the teleatlas.map but this didn't work. I'm using OSM.
You can edit them (as I tried earlier) - the problem ist just that apparently cycleways are addressed with STREET_OTHER_LINE_* - and I don't know what kind of ways are also included here.
It looks like you're new here. If you want to get involved, click one of these buttons!
