I would like the shell to support advanced job control: Ability to suspend processes (Ctrl+Z) and resume them (fg, bg). Display all active jobs with jobs. Interactively select which job to resume, for example via a numbered menu or a list to choose from, instead of manually typing fg %<job_number>. , support both foreground and background jobs and allow managing multiple jobs simultaneously.

You can leverage existing bash/zsh functionality as a base, but the key feature is interactive job selection.
