Thanks for this
I don't use Fork so I don't know if it works but if it's similar to trunk, should be fine.
I'll add more reviewers in case some of them uses Fork

I didn't test it (in the sense of using it), but I see the menu on fork. Useful change, thanks for that!

Awesome you added this, thank you. I also use Fork so can benefit from that addition as well.
