author here! it is my daily driver for quite some time; with that said, its current shape is a bit of a more recent development. Initially, I would manually handle jj workspaces and fire out screen/tmux sessions; but over time, I figure it would be nice to have an UI that I could browse from anywhere through a VPN.

It does take some investment -- by adding customizations through the overlay folder (`sgai/` directory at the root of the repository) -- but eventually it should be able to code in a way that you would approve in a PR.
