Its called "gh.nvim" and is a full featured GitHub integration for performing code reviews in Neovim. It takes a "commit-wise" approach, which is useful in most professional OSS projects where commits are the defining structure of the pull request.

Theres a good amount of initial features outlined in the demonstration video.

Gh.nvim is very new, and probably has a fair amount of bugs still, however I use it daily at this point. Could use some testers to find bugs/report issues/contribute fixes etc.
