Highlights

Code Formatter 1.9.2 is a little but important update bringing new themes, performance improvements, and various bug fixes. This version enhances the extension's reliability and adds visual improvements for a better user experience.



New Features

New Themes

Added support for 7 additional syntax highlighting themes:

Toggle Button Indicators

Active toolbar buttons now show visual highlighting to clearly indicate their ON/OFF state. This makes it easier to see which features are enabled at a glance.



Improvements

Performance Optimization

Improved Code Detection

• URL-Based Detection: Extension now detects code pages via URL patterns (GitHub blobs, raw files, Stack Overflow, Gists)
• Better DOM Detection: Improved detection of <pre> and <code> elements anywhere in the page

Bug Fixes
