That said, ianvoyager, you may want to give Knossos a try as well, as Nightmare mentioned.
In fact, if you could help me with testing the macOS version of Knossos 0.14.0, that would be great. 0.13.3 is the current version, because there's a macOS-specific issue that I've been trying to help ngld debug and that is blocking 0.14.0 from replacing 0.13.3. I'll move that conversation to PM, though, since it isn't relevant to this topic.
