Code Writer is a free text and code editor app with active syntax highlighting that updates as you edit documents and has 20 supported file types. A tabbed document interface allows for quickly switching between open documents.

The app has been built from the ground up with Windows 8 design principles in mind. It’s fast and fluid, and gives you the power to edit documents with features you’d normally only find in desktop apps. Code Writer is perfect for editing any text-based file, doing code reviews, or giving presentations with code samples.

The core text editor screen allows you to edit documents in full-screen mode without chrome distractions. Only the scrollbars and line/column display are visible by default. Find/replace and advanced features like tabify lines and convert case are available.
