## Description

The Code Editor Chrome extension is powered by the Monaco Editor, providing developers and enthusiasts with essential code editing tools right in the browser. Key features include syntax colorization for multiple languages such as HTML, CSS, JavaScript, TypeScript, JSON, XML, YAML, Markdown, and plain text. It supports IntelliSense for autocomplete, validation of code, and a Diff Editor for live side-by-side comparison of text.

Users can edit textareas on web pages or view page source and selected text with the enhanced Code Editor interface. Additionally, the extension supports various text encodings and extends its capabilities to compatible WebExtensions. Note that Android input method auto-suggestions may not always be compatible, and an optional File System Access feature is available through a companion extension.
