feat: Improve spacing and add 'Default values:' label

- Added newline after each section header for better separation
- Added newline after enabler prompts for visual breathing room
- Added 'Default values:' label before showing optional values
- Added newline before and after default values display
- Added newline after 'change values' prompt
- Overall much more readable with proper visual spacing

The output now has better visual hierarchy and is easier to scan.
