Hi @eugene-che

Thank you for queue improvement pull request. Your pull request looks good but several modifies are required for merge.

• Could you modify several single if conditional to be put on a separate line?
• Could you fix a typo (eidt -> edit)?

The following make option is very useful for checking the syntax and make code more beautiful with our coding style.

$ make beautify

thanks!
