Hi @Finii, hadn't discussed this with you yet, but hoping you are open to adding Departure Mono! It's a new font, but given the rate of adoption we have seen since launch, I believe it is merited. I am already using a self-patched version in my terminal and editor, as are many others.

Let me know if there's anything else I can do to get this PR merged!

[hackrmomo]

This would be a wonderful addition. I personally know many programmers also manually patching the font (myself included)

[tmahmood]

Yes! Waiting for it to get merged.

Thank you 💚

Need to get the release out, started to work through the still open Issues and got sidetracked 😬
