@drawBot That’s all! Not sure I did get the threading right, but perhaps it worked out. Similarities between most of these tools: - all support individual font files, or folders containing fonts - OTFs are preferred to TTFs, but both are supported - some proofs support UFOs and .designspace files - in that case, UFOs are preferred to OTFs. - all proofs write the resulting PDF to the Desktop and open it immediately. - for some, it’s possible to suppress PDF opening with a `--headless` option.
