dsh-chat-enhancer

A focused conversation enhancement plugin for DeepSeek Harness Web.

Features

Version 0.2 focuses on Mermaid code blocks in conversations:

• Renders mermaid, mermaidjs, and mmd fenced blocks as SVG
• Opens diagrams in a centered preview window instead of browser fullscreen
• Provides smooth pointer-centered mouse-wheel zooming inside the preview
• Supports click-and-drag panning, fit-to-window, 100%, and keyboard shortcuts
• Re-renders when the DSH light or dark theme changes
• Uses Mermaid securityLevel: strict and falls back to source on render errors
