please advise: line with draggable ends?

[mhaberler]

I want to extend the Foehn and Bise example plugin as an exercise to work along any two points - not just Zurich and Lugano

for that I need two points (ie markers) on the map with a line draw between them; line follows if end markers moved - exactly what Leaflet.DraggableLines does (demo)

however, this is pretty much already in "Distance and Planning":

Could anyone point me to an example how this is done with the current Windy Leaflet version? none of the public examples I perused do anything like that

Is there a list of "blessed" already-used Leaflet plugins I can safely reuse?

thanks in advance
Michael
