Oh, yes, please! Most of my work is in subfolders of a monorepo, and I've been missing the git integrations. This will be great!

FYI, if I understand correctly, I think that this would close (or at least address) #10154, #8418, #8275, #7816, #6762, #4419, #4672, and #5161. Phew!

Thanks for that listen @claytonrcarter!

Just wanted to say thank you for this! I updated and rebuilt, and git integration is working great in my monorepo projects. Thank you! 🙏 🎉
