Related problems

While I can add a line representing a moving vehicle (e.g. car, ship, plane, drone, spacecraft) path, if I want to denote the latest/last known position, I have two options:

1. create a separate point layer which represents the latest/last known position
2. change layer styling and "attachements", which does allow custom styling of the end point, but is convoluted.

Describe the feature request

I want an easy way to style the last vertex on a line or series of points with a custom symbol, which can rotate based on a property (if a point). This would be to support showing vehicle tracks (e.g. car, ship, plane, drone, spacecraft).
