I am working on a big project and therefore, sometimes I have a lot of branches (sometimes their name is close to another) that are in repo and under review. Therefore, unless I checkout to a branch and look at the logs, I don't remember what this branch does/fix/improve.
The Message box helps to attach Jira link (or more information) to the branch. Therefore, I don't need to checkout anymore to get more info about the branch.
