That was the tip of the iceberg!
@boldtrn agreed to the opinion to customize the GPX with Kurviger. Then you’ll ask the app too.
I respect all opinions, but I value more my development time to maintain everything thrown on app.
Website online formats should be separate from app and customized freely. App doesn’t use them.
And the best navigator is always the one that works without internet: routing, search, import / export.
That’s why HERE, OsmAnd, BRouter, GraphHopper (in the past) are considered top offline solutions.
