This pull is an attempt to switch away from the custom docker environment to use the @wordpress/env instead.

WP 5.5 is dropping jQuery migrate, so we need to check our code to make sure we're ready.

In order to help merchants in familiarizing with the various features of the plugin, it is interesting to work on an onboarding wizard as it is offered with the WooCommerce plugin.

In order to bring better compatibility for the korean shops and buyers, it would be interesting to format the name of korean buyers. For now, the format of buyers names is not ideal. For instance, in the order details, korean first and last names are formatted with a space. Also, in some cases, only the last name or the first name is displayed and may be offensive.

Describe the solution you'd like
Detect if the buyer's name is korean and format the name in order details and emails. (ex: 홍길순 instead of 길순 홍)

I have been reported that Naver TalkTalk feature doesn't work as expected. (banner and shortcode)

This plugin needs WordPress 5.0 which runs on PHP 5.3+.

Even PHP 5.3 has a lot of modern technologies like class autoloading, namespaces etc.

What do you think about leaving legacy technologies behind?

Following the latest update, the readme.txt file needs to be updated to mention Korean phone number formatting in key features of the plugin.

In most Korean shops during checkout, we are asked if we would like to issue a tax invoice (현금영수증신청) For manifest reasons, it is only requested when the payment method is bank transfer or virtual bank transfer. ( 은행송금 / 가상계좌 )

Although the issuance of tax invoice can be done directly from korean payment processors, it may be interesting to offer this option.

Describe the solution you'd like
Add a form for issuing a tax invoice during checkout.

Issuance (발급) / No issuance (미발급)

Individual (일반개인용)

• Resident ID number (주민등록번호)
• Phone number (휴대폰번호)
• Card number (카드번호)

Company (사업자용)

• Business license number (사업자등록번호)

In order to bring a better development workflow, and to ensure a better integrity of the next features, I think we should migrate from CSS to SCSS stylesheets.

Describe the solution you'd like

In order to improve the shipping experience, it would be interesting to add a "Shipping Notice" (배송메모) field as we can find on most Korean sites.

Describe the solution you'd like
By default, a similar field exists in WooCommerce but it prompts the user to type the note. This new field would prompt to select an "option" from a list, such as:

• Please contact me before delivery (배송 전 연락 바랍니다)
• Leave the package to the security office (경비실 에 맡겨 주세요)
• Please put the package in front of my house (집앞 에 놔 주세요)
• Please put the package in the delivery box (택배 함에 놔 주세요)
• If I'm not home, please call me (부재시 핸드폰 으로 연락 주세요)
• Please leave the package at the security office in case I'm away (부재시 경비실 에 맡겨 주세요)
• Please put the package in front of my house in case I'm away (부재시 집 앞에 놔주세요)

Of course, the list could be edited with a hook filter to allow plugins & theme to modify it.
