It is really a source of annoyance to have to drill down through several layers of menus to open TFS sourcecontrol explorer. Especially when this windows is used over and over again (a lot of times during the day).
To add it to your menubar for easy access; perform these actions.
1) Add a new button to the menubar you wish the SourceControlExplorer to be associated to:
2) Find this item in the “Add Command” option.
3) You are done.
