When it comes to do some corrections after a code review, it can be painful to switch between GitHub and your IDE and browse the file tree to find the right file to update.
To improve this workflow, I recently developed a browser extension allowing to open GitHub links directly in VS Code and put the cursor at the desired line when possible.
Obviously this extension will only work if the repository is cloned on your computer. You can edit the local repositories path in the extension settings.
Feel free to open an issue on the GitHub repository if you detect a bug or a missing feature!
