I often want to tell other developers on my team to look at or pull a specific branch. I'll send this branch's text name via email or chat.
This requires me to type out the branch name. If the branch name is long or complicated, typing it out is very annoying:
The Branch Sidebar's right-click menu should be given a "Copy Branch Name to Clipboard" option. This option will copy the branch's name to your clipboard.
You can then paste the complicated branch name into your email or chat program.
This would be similar to the "Copy SHA-1 to Clipboard" option when right-clicking a commit. Extremely useful command in both cases.
