Please, add a "Rename branch..." option to the Graph's contextual menu (right-click) for local branches.

It should open a modal dialog with a textbox to edit the local branch name:

This would be super useful because developers usually look at branches from the Graph.
Otherwise after seeing the branch to rename, the user would have to locate that branch in the "Branches" side panel and rename it from there, the problem comes when we have hundreds of branches and locating the same branch we already located in the Graph is harder with many branches having very similar names.
Also the hard-refresh of the Graph that comes after renaming a branch doesn't help to keep the focus on what the user was doing.
