Add a `Legend`
Use case
When enabling various overlay selection modes, I personally often find it unclear what exactly certain colors mean.
Proposed Solution I would appreciate a drop-down list or slide-out panel explaining the meaning of each color added to the map by enabling a profile via the overlay selection feature.
I know it's not exactly what you asked for, but there is a community-maintained color legend in the OSM wiki: https://wiki.openstreetmap.org/wiki/StreetComplete/Overlays
@FloEdelmann, thanks, that's better than nothing! As a temporary measure, I think it would be appropriate to add a link to this page in the app (with an external link icon [1]).
