Some (importable) sample proofs in the "plain" notation are here. Note that proofs can also be exported in "pretty print" notation (with unicode logic symbols) or LaTeX. See this pdf for an example of how Fitch proofs typeset in LaTeX look. To typeset these proofs you will need Johann Klüwer's fitch.sty.
