I have a multi-step workflow that I want to monitor with zellij. If I could tell zellij to execute my tabs in order, rather than in parallel, I can do some interesting things, like effectively run my CI pipeline as a zellij workflow, where can I watch the steps, see the fanout as multiple panels, and so on.

Particularly, I'd like to combine this with "keep-open" or "hold" functionality so that I could go back and review the finished output from earlier steps.

I could probably coordinate this myself with sentinel files or a named pipe or something like that, but it'd be nice to have it in zellij, possibly. Alternatively, I'd understand if this were considered out of scope.
