Github File Tree Extension for Chrome

See PR Folder Structure in Chrome

This Chrome extension enhances the GitHub code review experience by displaying a folder tree of all files in a pull request directly alongside the code changes. Designed for developers and engineering teams, it simplifies navigation through complex PRs with large file structures. The tool addresses the common challenge of losing context when reviewing files scattered across multiple directories. Ideal for collaborative development workflows, especially in large-scale projects where file organization is critical. The extension integrates seamlessly into the GitHub interface without requiring configuration, allowing users to quickly identify file relationships and track changes across folders. It is particularly useful during code audits, team onboarding, or when reviewing contributions from unfamiliar parts of the codebase. By visualizing the file hierarchy, it reduces cognitive load and helps maintain focus during detailed reviews.

Key Features & Capabilities

• Folder Tree Visualization – Displays a collapsible tree view of all files in a pull request, showing directory structure and file hierarchy directly on the Files tab.
• Contextual Navigation – Enables quick jumping between files and folders without leaving the review interface, improving workflow continuity.
• Seamless GitHub Integration – Works automatically within the GitHub web interface with no setup or configuration required.
• Real-time Sync – Updates the folder structure dynamically as changes are made to the PR, ensuring accurate representation.
• Minimal UI Overhead – Maintains a clean layout that does not obstruct the code diff or file content.

The extension is ideal for developers reviewing large PRs with multiple nested directories. For example, when auditing a refactor involving dozens of files across several subfolders, the folder tree allows users to instantly locate related files and assess structural changes. Teams managing complex monorepos benefit from the ability to visualize file relationships without switching contexts. The feature also supports onboarding new contributors by making codebase structure more transparent during review sessions.

User Interface, Workflow & Performance

The user interface is unobtrusive and integrated directly into the GitHub Files tab. A vertical sidebar displays the folder tree, positioned adjacent to the code diff view. Navigation is intuitive: users can expand or collapse folders, click on files to open them, and maintain focus on the review process. The layout is responsive and adjusts to different screen sizes, ensuring usability across devices.

Workflow efficiency is enhanced by reducing the need to manually navigate between files or use external tools to trace directory paths. The extension operates in the background, with no visible performance impact reported in the available documentation. The developer did not specify resource usage details. Performance observations are based on general software behavior patterns. Stability appears consistent, as the extension runs without reported crashes or interference with other GitHub features.
