If you're staying in a city for a few days, you can add "Free spots" to show where you've been without having to trace a return itinerary.
You can also attach Free spots together to trace a secondary itinerary.
- open your admin map
- select a spot
- click on "Attach" > "Free spot"
- Add a new spot
- click on "Save"
The new spot will be added below its parent spot.
You can click on "Edit" to change the transport mode, the icon, etc. or hide the line completely (select "Line: Hidden").
Tracing secondary itineraries
If you attach a new Free spot to an existing Free spot, it will create a chain of Free spots that can let you trace secondary itineraries.
Beware, this is an advanced feature. Make sure you understand how to trace your main itinerary first.
