- 앱 안 브라우저 (Edge WebView2): 동영상 페이지 [다운로드], 즐겨찾기
  (표시줄 · 폴더 · 실행 취소 · Chrome/Edge/Whale 가져오기), 로그인 쿠키를
  cookies.txt 로 내보내 yt-dlp 와 공유
- 자막 번역: 있는 자막을 NLLB 로 번역해 jj_mkv\파일명_언어코드.srt 로 저장하고
  MKV 자막에 추가, 인터넷 자막을 받을 때 한국어로 함께 번역
- 작업 대기열: AI 자막 · 자막 번역 · MKV 만들기를 차례대로 실행
- 브라우저 화면 분할 [작업 현황]: 작업 · 편집 목록 · 다운로드 진행
- 다 받은 동영상을 편집 목록에 자동 추가 (설정)
- 설정: 시작 화면, 홈 주소, 외부 브라우저
