The redesigned Team Explorer in Visual Studio 2013 provides a sub-optimal viewing experience when needing to work with a large number of builds. This project utilizes your build definition naming conventions to build a tree view section into the Builds page in Team Explorer.
Currently the only features that are supported are simply a hierarchical view of the build tree using the '.' as the separator character and you can view the queue, edit the definition, and queue a new build. We've got a couple items in the queue that we think many users will enjoy (such as the ability to choose the separator character and using that across your entire team).
