Ability to select branch(es) using commands

[sax]

Describe the improvement that you'd like

It would be nice to be able to select branches using keyboard commands.

Additional context (optional)

My team does a daily diff of multiple repos, using this extension. One bit of hassle is that some of the repos use a lot of branching, but we only want to see main. So every time we open git graph, the first thing we do is use the mouse to click around.

If there was an command that could pop up the branch selection dropdown, then use arrow keys to select a specific branch, it would make our daily workflow easier.

:bow: Thanks for this extension by the way. It's incredibly useful.
