CodeMirror 3.13 for MODX Evo: Better Highlighting and Full-Screen Editing

This CodeMirror update was a meaningful editor upgrade for Evolution-era projects: better syntax support, MODX tag highlighting, and a much more usable editing experience.

The old custom Evolution ecosystem spent a lot of energy improving the editing experience, and this CodeMirror update is a good example. The package introduced a stronger code-editing workflow directly inside the manager, rather than treating code fields like plain textareas.

Highlights

syntax highlighting for JavaScript, CSS, JSON, XML, and HTML-like content
MODX tag highlighting
active-line highlighting and configurable tab size
folding, breakpoints, line numbers, and full-screen mode
better keyboard shortcuts for real template editing work

Why it mattered

For teams editing chunks, snippets, and templates inside the manager, these changes were more than cosmetic. They reduced mistakes, sped up navigation, and made the editor feel closer to an actual development tool.
