@Lilja to Quit fzf, you need to select bottom option - === Quit sessionizer ===
What you point out is why this script exists. Zellij doesn't support switching sessions, so this script emulate it. By exiting Zellij you end up in project picker to select another project and open its session or create new one.

In the end I abandoned using Zellij, why:

1. must have for me, that's impossible to emulate in Zellij:
   • tmux provides nice way for fast switching between current and previous session
   • fzf is running inside tmux, so if I change my mind, I can just press Esc to return to current session
2. nice things:
   • tmux covers all my needs or Zellij doesn't provide anything new, that's useful for me
   • I don't like Zellij view: all this green frames or lines, and I don't see easy way to customize it
   • I don't like keybinding: there're a lot of them and they conflict with what I set in Vim, so I need to always keep Zellij in locked mode and modify keybinding for all mode transitions: a lot of work, complex custom config. I don't see a need in all these mode transitions in the first place
