Customize track drawing, gpx, where did I stop, speed color scheme.

[Allroads]

Imported a GPX track.

I like to see where I stopped, 0 km/h. example colored dot or so, maybe icon.

The car scheme, which color at what speed in displayed in screen, but is there a info table to look at.

Can I changed the such color scheme. Or make my own scheme.

Stopped is maybe 0-3 km/h, gps is most oft the time moving around.

I placed it under core, thought that this was not a part of the gpxedit plugin
