Herdr made it quite nice and easy to have different worktrees/spaces. Eg. I wrote a simple plugin that rsyncs the dev repo (including uncommitted, untracked and gitignored files like `.env` and generated code, so it's ready to use right away) and create a git worktree and open it as its own workspace in the sidebar. I see Rex has the concept of sessions and tabs within it, so am wondering how are people working and switching worktrees within it, automating flows etc?
