Mermove for GitHub

Pan and zoom Mermaid diagrams rendered on GitHub.

Mermove for GitHub is a Chrome extension for panning and zooming Mermaid diagrams rendered on GitHub. It is useful when a large flowchart, sequence diagram, or other Mermaid diagram does not fit comfortably in GitHub's viewer and you need to inspect its details without leaving the page. ## Controls - Left-drag the diagram: Pan - `Ctrl` + mouse wheel (`Command` + mouse wheel is also supported on macOS): Zoom around the pointer position - GitHub's existing Reset view button: Reset both GitHub's view and the extension's transformations Dragging does not start from Mermaid nodes that are links. A click and a drag are distinguished by a 4-pixel movement threshold. ## Scope and Permissions The extension runs only in GitHub's dedicated Mermaid renderer at `viewscreen.githubusercontent.com/markdown/mermaid`. It does not run directly on `github.com` pages and does not request additional browser permissions.
