Double click to switch branch (maybe also to commit)

Thank you for your great work. git-log--graph is great (and by the way may teach users the git commands ;) )

I have a small suggestion to improve usability and make plugin a bit more intuitive.
Adding a double click support which could be used for quick switch between branches (when clicked on branch label) and maybe also commits (this use case is not as important in my opinion).
