 - `theme_display_user`. If set to `yes`, display username always, if set to `ssh`, only when an SSH-Session is detected, if set to no, never.
 - `theme_display_hostname`. Same behaviour as `theme_display_user`.
 - `theme_show_exit_status`. Set this option to `yes` to have the prompt show the last exit code if it was non_zero instead of just the exclamation mark.
+- `theme_show_job_number`. If set to `yes` this option displays the number of currently running background jobs next to the percent sign.
 - `theme_git_worktree_support`. If you do any git worktree shenanigans, setting this to `yes` will fix incorrect project-relative path display. If you don't do any git worktree shenanigans, leave it disabled. It's faster this way :)
 - `theme_use_abbreviated_branch_name`. Set to `yes` to truncate git branch names in the prompt.
 - `fish_prompt_pwd_dir_length`. bobthefish respects the Fish `$fish_prompt_pwd_dir_length` setting to abbreviate the prompt path. Set to `0` to show the full path, `1` (default) to show only the first character of each parent directory name, or any other number to show up to that many characters.
