Translate, Clean, and Convert Subtitle Files with Elegance

SRT4U is a premium desktop application built with Python 3.13 and PyQt6, designed to process subtitle files with a focus on speed, reliability, and a stunning Glassmorphism user interface.

The latest version features a complete architectural overhaul:

• Premium UI: Ultra-modern dark theme with translucent "Glass" cards and smooth gradients.
• Architectural Purity: Strict separation between core processing logic and the user interface.
• Parallel Translation Engine: New multi-threaded core for significantly faster translations.
• Enhanced Performance: Optimized for Python 3.13 with native PyQt6 threading.
• Bundled Executable: Easy distribution using PyInstaller.
