  description

  Stop suffering with Miva Merchant's default code editor.
  
  Writing complex code, mixing HTML, CSS, JavaScript, and Miva Script (<mvt>) in a basic, unformatted textarea is a nightmare for productivity. Mutant Miva Editor by IZOFER solves this by injecting a powerful, dark-themed CodeMirror environment directly into your Miva admin panel on-demand.
  
  Designed specifically for Miva developers, this tool replaces the clunky legacy UI with a fluid, modern development experience without breaking native backend functionalities.
  
  Key Features:
  Smart Auto-Completion: Automatically closes brackets {}, (), [] and standard HTML tags to speed up your workflow.
  
  Miva Script Aware (Blacklist): Intelligently ignores <mvt> tags during auto-completion. You can write your server-side logic without fighting the editor's auto-close behavior.
  
  Live Customization: Use the extension popup to instantly toggle line wrapping, active line highlighting, and set custom editor dimensions (width/height) without needing to refresh the page.
  
  Syntax Highlighting: Full support for HTML, CSS, JS, and XML mixed environments (Monokai theme).
  
  Native Controls Intact: Seamlessly transplants Miva's native "View Version History" and other essential mini-controls so they float cleanly over the new UI.
  
  Privacy & Security First:
  This extension respects your code and your clients. It runs 100% locally in your browser. It does not track you, does not collect analytics, and does not send any code, credentials, or data to external servers.
  
  Developed with passion for the developer community by IZOFER.

  🚀 What's New in Version 2.2.5:
  Bulletproof DOM Synchronization: Completely rebuilt the core injection engine to deeply integrate with Miva's custom <mm-texteditor> Web Component. The editor now perfectly captures data even when Miva loads templates dynamically via AJAX or destroys/recreates the native DOM tree. No more empty editors!
  
  Instant On-Demand Activation: The CodeMirror environment now spawns instantly the exact millisecond you toggle the switch in the extension popup. Zero page refreshes required.
  
  Invisible Proxy Sync: Typing in CodeMirror now performs deep attribute updates to Miva's hidden native components, ensuring standard "Save" and "Update" buttons work flawlessly on the first click.
  
  Popup UI Fixes: Suppressed harmless Chrome Developer Console promise errors when utilizing the popup outside of Miva Merchant tabs.
