I find myself reconnecting all wires in a sequence or adding a new sequence when I really just want to insert a new execution pin. So, a context menu item to insert a pin would be great.

One of the things I often do with sequences is to put reroute nodes just in front of them so I don’t have to snake lines back and forth when it comes time to add or reorder.
