Difficulity to overview road network

In the ME the "ALT" view not helpful enough to overview the road network.

The most confusing thing is the elevation lines with the same color as roads.

I suggest an "ELEVATION LINES" "LAYERS FILTER" to the "MAP OPTIONS".

The country border also close in that color -> in 1.5 was distinguisable wide red line.

I suggest a "BORDERS" "LAYERS FILTER" to the "MAP OPTIONS".

LAYERS FILTER seems to be WIP:

-forest areas not hideable at max zoom, only individual trees

-railways filter working only in close zoom, railway parts are missing
