Add a MOVE method to the Nintex Web Service
Being able to MOVE an item or document in SharePoint maintains the version history of that item as opposed to a COPY that creates a new item and doesn't maintain that history. Currently MOVE can only be done using Content and Structure or WEBDAV. Being able to automate this in Workflow would be very useful.
Definitely. Please also ensure the Move and Copy actions return the item ID in the target list/library. Currently Copy doesn't do this which is a pain.
