Possible to customize Terminal context (right-click) menu?

First things first: I don't know if it is per-user configurable.

But a workaround is possible thanks to the easy to edit XML files, which describe the user interface. On Ubuntu 12.10, in the file /usr/share/gnome-terminal/terminal.xml simply move the line <menuitem action="PopupCopy" /> to the top below <popup name="Popup" action="Popup">. Or to be semantically consistent:
