 - `fish_prompt_pwd_dir_length`. bobthefish respects the Fish `$fish_prompt_pwd_dir_length` setting to abbreviate the prompt path. Set to `0` to show the full path, `1` (default) to show only the first character of each parent directory name, or any other number to show up to that many characters.
 - `theme_project_dir_length`. The same as `$fish_prompt_pwd_dir_length`, but for the path relative to the current project root. Defaults to `0`; set to any other number to show an abbreviated path.
 - `theme_newline_cursor`. Use `yes` to have cursor start on a new line. By default the prompt is only one line. When working with long directories it may be preferrend to have cursor on the next line. Setting this to `clean` instead of `yes` suppresses the caret on the new line.
+- `theme_newline_prompt`. Use a custom prompt with newline cursor. By default this is the chevron right glyph or `>` when powerline fonts are disabled.
