"Highlight" visible only for a tour
User should be able to create point or segment with text and photos but it will be visible only in context of a tour. This is very useful to describe the route, e.g. "here you should see a tree and turn right after it" or "be aware that there is avalanche risk here"
This can be a workaround for the other critical missing feature below, e.g. "Here do not follow Komoot, turn left right after the end of forest on a nice single track not on the map!"
Later this can be used by komoot users to create beautiful travel diary about their tours - including text for specific point\segment, photos, location, time/duration to get there, etc.
I can think of another option: what if tour comments can be not only a text but a text with a point or a segment attached to the text
Something like "notes", "warnings", etc - for a point or a segment
This will enable people to create some kind of a travel history, e.g. here we've seen an animal steps; we have met a shepherd who told us a story about ... Etc
