Black-white background layer on main map?

Fantastic @moenk! So simple, yet so helpful.

Would you mind putting the code on something like GitHub, so that others can contribute?

There is a few small things I would like to see:

  • Add a manifest.json so that it can be installed as a “proper” web app on mobile phones.
  • Lighter background map. The current one shows the tracks very nicely, but makes it hard to recognize the streets (especially outdoors).
  • Labels layer on top of the tracks, so that street names can be read on streets that are covered in many tracks.
