It would be nice if the route description included some indication when turning of from a motorway or other high level highway on to a link road.

e.g.

Something like "Keep right" instead of "Continue". If there's a highway=motorway_junction tag on the junction node then it could display the name or ref. Don't know how hard it is to detect such junctions if they are not motorway junctions. Perhaps support for hinting with junction=yes on the connecting node would be a solution?
