I agree with you, it is not the task of version control directly.

But indirectly, we can look at it like a log. special kind of log that is not being assigned to a commit specifically but to a branch. Although, I don't think we have such a thing in the Git.

Thanks for your explanation.

Let's assume that I set a meaningful name although it is difficult to keep it short.

Then a different situation might happen for the branch.

1- If I am not done with the branch (In case something urgent happened or I need to leave this branch for a few days), then I want to add a few links into it. Somethings like a link to the Jira ticket, wiki, and Slack (link to a discussion). I might want to write some sentences, too, to summarise what I have done and what I need to do later.

2- If I am done with the branch but I want to keep it for my later reference, then I might want to add some notes for the future.

I am not sure if it makes sense to the majority of the users but having this ability helps me a lot.

I am 101% agree. 

It took me around 1-2 minute to find it.

I went to Help menu, when I didn't find the link then I opened my browser, came into .wwwsyntevo.com then opened ContactUs page to report it. then I found feature request over there.

So, please Vote, everyone.
