Open file paths in Sublime Text 3
Open in Sublime provides a context menu to open file paths in Sublime Text 3. Right click any file in GitHub or code block in GitHub to open that file locally in Sublime Text. A local checkout of the GitHub repo is required.
Also right click any absolute file path (such as shown in a PHP error) to open it in Sublime Text.
