It's a good extension...but not enough yet ;)
It could be a good successor of "Copy Plain Text" (witch btw *DOES* work on 3.0.1 for me, it's just need max. ver. boast).
I would like to see some more changes to behave more like it's predecessor:
* place context menu entries below standard copy entry and add menu entry in menu bar "Edit"
* there are some nice options in CPT like replace standard copy function and remove unwanted spaces/lines.
Keep up the good work! :)
