Color-coded track gradient for imported GPX routes

Hi everyone,

First of all, thank you for developing and maintaining this app; it brings tremendous value to navigation on Garmin devices that lack native mapping features.

I would like to suggest a feature enhancement regarding route rendering: adding an option to display terrain slope directly on the route line using a color gradient when following an imported GPX track.

Could this be possible? Having the route line colored by inclination allows athletes to assess upcoming terrain profile at a quick glance without needing to switch data screens while doing the activity.

Thank you for considering this addition, and keep up the great work on the application!
