Directional Arrows While Navigating

I'd say zoom in a bit more? 

I can't tell how densely packed your roads are, but in the netherlands my only real gripe with these is it doesn't remember the level of zoom I set when I allow it to auto zoom in or out.

As for the progress I'd use a distance traveled and distance to go data field, maybe in the edge maps datafield from ciq?

It's not a matter of zooming...

Another example: Where to go at the point where the course crosses itself.

Problem is that the directional arrows are placed over the entire course!

It's pretty obvious that you have to go straight ahead at the crossing...
