Feature request: Add context menu to branch name in lower left

[dougmartin]

Version 1.11 changed the default action when you clicked on the branch name on the lower left from opening an input with git checkout already filled to an input for the git checkout command itself. The previous pre-filled input was nice in that you could replace "checkout" with "branch" and create a new branch.

Instead of cluttering the new popup ui with a branch option you could add a context menu to the branch name in the lower left corner that would contain branch and optionally other common commands which you can access now in the ellipsis menu in the git pane (note: branch is not available right now in the git pane ellipsis menu).
