In the tread "Help/FAQ" I post this :
With O 3.3.1419 :
In the waypoint manager, I have a large amount of waypoints and I wish I could hide.
I'm forced to hide them one by one?
Is it possible to hide them with a single
command after you have selected all.
(there is no button "Hide All" and there is no menu to do this)
I searched the opencpn
.org website but I did not find any explanation to my question.
In the absence of response, I create a tread apart.
Thank by advance if somebody can help me.
