Hi Felix, OK, I am happy to hear feedback regarding the latest changes the branch. Next planned step is to check if the simplify4.patch still improves things and maybe improve it further.

I'm waiting for updates on the new branch to test things. I still feel level>=1, the higher the level the less exact it needs to be. It just needs to be small and beautiful from resolution 21 and lower. While actually driving/riding/walking you will always use 24-22 (even 22 only in car I feel. Maybe 21 on highways). Those levels are important on PC and GPS device for orientation. And while actual switchback turns on a road would be quite worthwhile, those zig zag things aren't.
