반응형 디자인: 현재 UI는 고정된 크기로 설정되어 있습니다. 다양한 화면 크기와 해상도에서도 잘 동작할 수 있도록 반응형 디자인을 적용하는 것이 좋습니다.ㅣ
로딩 스피너 및 상태 표시: 크롤링 중에 진행 상태를 더 직관적으로 표시하기 위해 로딩 스피너나 실시간 진행 바 등을 추가할 수 있습니다.ㅣ 스케줄링 유연성: 스케줄링 기능을 더 유연하게 만들어 특정 요일이나 복잡한 반복 규칙을 지원할 수 있습니다.ㅣ
데이터 정제 및 분석 도구 통합: 수집된 데이터를 더욱 효과적으로 분석하고 시각화하기 위해 추가적인 분석 도구나 데이터 정제 기능을 통합할 수 있습니다. ㅣ 자동화된 테스트 기능 도입: **단위 테스트(Unit Test)**와 **통합 테스트(Integration Test)**를 도입하여 코드 변경 시 발생할 수 있는 버그를 사전에 방지하고, 코드의 안정성을 높일 수 있습니다. ㅣ (https://codebeautify.org/htmlviewer 이거 hlml 보여주는 사이트 거든?? 한 번 넣어보셈 ㄱㄱ)ㅣ

여기 크롤링 코드 보면 다음 페이지 넘어간 뒤에 자동으로 크롤링이 되어야 하는데 다음페이지로 넘어가니깐 UI 자동으로 꺼짐..ㅣ
창을 잘 관리 할 수 있게 창 조절 기능을 추가하셈.. ㄱㄱ 그냥 옆에꺼도 볼 수 있게 밑에 옆으로 가게 하는 그런 스크롤바 같은 거 있잖아 그런 거 ㅇㅇ

아님 이 사이트를 바탕으로 html 보여주는 방식으로 ㄱㄱ      이걸 바탕으로 밑에 코드 개선ㄱㄱ   그리고 니가 써도 되는 용량이 다 차면 무조건 파트 1로 끝내 알겠지??                             // ==UserScript==
