How to turn on\off red line after the tracker
When moving, a red line will remain behind the tracker's icon.
This is not a full-fledged movement track, but is made only for a more visual visual perception.
The trail can be disabled. To do this, in the top control panel, click on “Track tail”.
If the text is grey, then the tracker will no longer display a red trail.
To turn on click on “Track tail” and the line will be displayed again.
The track tail is not stored and is cleared when reloading the page and enabling/disabling it on the map. To view the full history of the movement, display the track on the map.
