Currently, it seems that public transport POIs are not click-able. They only appear on the map at certain zoom levels but cannot be interacted with. See two examples of this below.
London
Munich
Interestingly, while train/metro stations are not click-able, airports are:
In addition to all the standard information a click-able POI should contain, live timetables (if APIs are free/very cheap) for major cities would be a plus too — although since Kagi Maps is not a directions service, I would understand if this isn't a priority.
Further to the above, though, I also notice that some landmark POIs were not click-able. You can see this behaviour in the screen recordings. Why is this?
Relates to this post in spirit but not in specifics: #9319 (Public transport layer for Kagi Maps). This feature would be required for a layer to offer substantive utility.
