Global timeline

i would know if is it possible to have a global timeline for all layers, i see only a timeline for a single layer and i must select another layer to see its waypoints. I’m searching a way to see all waypoints for all layers in a single dock.
Thanks in advance

Group layers and select it from the layers panel, you will see all waypoints from this group.

Nota : missing some tooltips to know “who is who” and a way to select a single waypoint when multiple are on the h:m:s:f
