This extension adds an Browse button to the toolbar which allows you to browse the current GitHub repo using Source Code Reader.
Source Code Reader is a web application which basically allows a user to open a publically hosted .NET C# project on Github and navigate through the code seamlessly. It allows a user to navigate directly to the implementation code from the calling code with single click (similar to the Go To Definition feature available in Microsoft Visual Studio).
Source code hosting providers like GitHub, Bitbucket, CodePlex and Google Code only provide provide basic file browsing capabilities. Source Code Reader does much more than files browsing; it understands the semantics of the code to give superior code navigation functionality.
