There is already a way Noté 4 sur 5 étoiles

Hello! On its own, this is a good idea, but you can already get an "Edit as new" button if you use the ToolbarButtons extension which has all kinds of useful buttons in it. As far as I can tell the authour keeps up on his versioning too. I give a four star here because the idea is very good, but I have not tried it myself on account that I use the other addon instead.
