There is a new ovlerlay style available in the MapOSMatic overlay selection now:
The Waymarked Trailsi Hiking style
The Waymarked Trails database is also covering the full planet, and updated every 15 minutes.
So far only the hiking style is provided, the other route types (cycling, skating, …) are to follow over the next days at about one style per day.
Unfortunately the route symbol shield placing isn’t perfect for print output yet, I may still have to tweak the original style sheets a bit to get output more suitable for printing.
