Answer 1

I had no luck with diffoff, but I just learned that :Gedit with no argument will bring you back to the working-directory version of the file, as opposed to some earlier version you were reviewing.

And as q (no need for :q) will close the diff sidebar, you can do q followed by :Gedit to get rid of the sidebar and then go back to the current version of the file.
