View of the track line

Hello, could you help me,
how can I change the view of the line and arrows of the track line?
If I need to change the files, then where and in what lines?

This is only on replay, how can we make it more dynamic on live?

I also want to understand in which file I can add the track layer, which is on the right in the picture, to the main screen for the current day.

Daniel Wendell Are you referring to live routes? https://github.com/traccar/traccar-web/blob/master/src/map/main/MapLiveRoutes.js
kot-tok I didn't understand your question.

@Cristian yes to live routes. So would this be where we can change the route line live?
