Silex v3.7.3 — CSS Variables and many bug fixes

CSS Variables plugin lays the foundation for themeable templates and upcoming dark mode. Plus MCP integration for AI agents and a long list of bug fixes.

🎨 New plugin: CSS Variables (foundation for theming)

@silexlabs/grapesjs-css-variables lets you define and reference CSS custom properties (variables) directly from the style manager.

Why this matters:

• Theme-able templates — build a template once with named variables (--primary-color, --font-heading, etc.), then adapt it to a brand identity in seconds by just changing variable values
• Dark mode foundation — variables are the standard way to implement light/dark themes; Silex now has the primitive needed

🤖 MCP / AI Integration

Silex exposes editing capabilities through the Model Context Protocol so AI agents can interact with selectors, styles, and content. Available standalone (stdio) and embedded in the editor.

🐛 Notable Fixes

• WebKitGTK drag-and-drop now works (Linux usability)
• FTP save when src/ folder doesn't exist (#1644)
• "Default styles missing randomly" — root cause fixed
• Elements no longer get auto-generated IDs unless explicitly set
• Selectors: :hover without explicit selector (#1643), uppercase classes, body styling
• macOS: file:// links and logging
• Data source UI: WP backend types, dropdown positioning
• Import image by URL no longer breaks publication
• Code selection/editing in Settings panel

🖥️ Early preview: Silex Desktop

A native desktop app (built with Tauri) is included as an early preview for testing. Not yet production-ready. Available in Downloads below.
