Team Explorer Enhancements
This tool provides additional Visual Studio menu options and functions
to support finding files under version control by status or wildcard,
opening a folder using File Explorer from the Source Control Explorer
context menu, and labeling files and folders in Source Control
Explorer. Clone builds definitions easily and copy work item paths.

and components, create workspace templates, and track your sprint
