In relation to what is stated in github on
bus, when you select one more nodes the pins remain active, in the small nodes or in the buses, if you click the link is linked.
It would be an option when selecting a node to deactivate the pins and deselect with ESC or click outside.
In large patches the size of the nodes is reduced and you have to aim trying not to touch the pins, to move or copy.
Currently I must click outside to unlink the connection.
