Just a suggestion here from a confused user.
When you duplicate a form from the list view, you are redirected to the original version of the form. If you duplicate the form while being in the edit view, it still stays in the same editing view. Especially the first one has made me mess up many forms when I don't remember that it takes you to the original one. It would be awesome to be redirected to the 'copy' instead or maybe just taking you back to the list view where you can select the form you want to edit.
