remove node from way

[Oli-Wan]

I'd like an entry in the tools menu to remove one node from a way: keep both the way and the node with all their respective properties and relation memberships, but have the node no longer be part of the way.

This boils down to deleting a single "<nd ref=...>" line, but (as far as I know) cannot be done in JOSM directly. Instead, you have to duplicate the node, manually edit the new node's relation memberships, then delete the old node, which ist needlessly cumbersome for such a trivial task.
