It is also hard to pick out trails which are green on background of lighter green sometimes when outside so a different colour or a thicker line would be useful
Yes, that is exactly what I have complained about many times. Trails are too thin and the contrast between similar colors isn’t good enough. That is less of a problem when having a navigation route, but using the map without a navigation route is problematic due to poor contrast of “green on green” trail rendering. This applies to both Light and Dark maps. Also this partially applies even to High Contrast maps because trails are too thin and still not high contrast enough.
