✨ Features

• 📊 Live word, character, sentence & line count → 📊 실시간 단어, 문자, 문장 및 줄 수
• 🔍 Keyword density calculation → 🔍 키워드 밀도 계산
• ⏱ Estimated reading time (200 WPM) → ⏱ 예상 읽기 시간 (200 WPM)
• 📂 Open & save .txt files → 📂 열기 및 저장 .txt 파일
• 🌙 Light / Dark mode toggle → 🌙 라이트 / 다크 모드 전환
• 🧹 Clear text with confirmation → 🧹 텍스트 지우기 확인과 함께
• ❓ Built‑in help dialog → ❓ 내장 도움말 대화창
• 💻 Fully offline & cross‑platform → 💻 완전 오프라인 및 크로스‑플랫폼

🧰 기술 스택

• Python 3
• Tkinter (GUI)
• ttk (테마 위젯)
• sv‑ttk (현대적인 밝은/어두운 테마)
• threading (논블로킹 업데이트)

📦 요구 사항

Only one external dependency is needed:

pip install sv-ttk

🏗️ App Architecture

The app is split into logical sections:

1. Helpers – status updates & resource paths
2. Core Logic – text analysis & keyword density
3. UI Sections – text input, statistics, actions
4. Theme Engine – light/dark mode switching
5. File Operations – open, save, clear

This keeps the code readable and extensible.

🚀 확장 아이디어

• CSV로 통계 내보내기
• 키워드 발생 횟수 강조
• 실시간 가독성 점수
• PyInstaller로 .exe 패키징
• 드래그 앤 드롭 파일 로드 추가

🧠 최종 생각

Tkinter가 구식일 필요는 없습니다. ttk + sv‑ttk를 사용하면 Python만으로도 현대적이고 유용한 데스크톱 도구를 빠르게 만들 수 있습니다.

이 글이 마음에 드셨다면 자유롭게:

• 포크하기
• 확장하기
• 패키징된 데스크톱 앱으로 만들기

즐거운 개발 되세요! 🛠️
