Copy branch name

hi,

I have suggestion that would be helpful to me and I think other developers.

When I access particual PullRequest and see some comment under it, I usualy want to pull this branch and do some changes on it.

Than I try to Copy branch name from here (see image) and it is hard to select it, usualy copied text has too much characters..

It would be helpfull to have button with "Copy branch name"

so I could easily go and: git pull <pasted branch name>

thanks
