An endorsement: I freaking love Zellij. I mainly use it like one might use Tmux, to keep remote sessions alive so I can reconnect to them from another host than where I began the session:

* Ssh in to myserver.cloud from my laptop. Run Zellij. Fire off various long-running processes in multiple tabs.

* On my commute home, ssh in from my phone, run `zellij attach`, and check on the status of those processes.

* Once home, ssh in from my desktop, run `zellij attach`, and continue where I left off earlier.

Tmux is nice, but Zellij fits my brain a lot better. Plus, it has a lot of UI affordances to discover features without me having to memorize keystrokes. I use these kinds of tools often enough to care about them, but not so often or in such depth that I'm any kind of a power user. There are certain things I do so rarely in Tmux that I have to look up the manual every single time I do them. With Zellij, I don't have to.
