"online live reloading apps" => trying to get my head around this workflow. so the disk is shared across these? so do you still have the problem of say running a "main" version of an app, and it's weird experimental version of that same app? because they still have to live in different folders/worktrees? that's where I get stuck a little trying to enable things like this for others. right now, I've got people a system we can spin up N "vms". but it's not persistent storage if the vm goes away. it's whatever version exists in their GitHub branch. hopefully if they hack the vm app they commit and push back to the repo.
