We no longer need to cut and paste MR URLs into Slack manually. Axolo also reduces button-clicking in the GitLab UI, because Slack can be used to assign a Reviewer and also Approve an MR. We no longer need to watch for email notifications and context-switch to the GitLab UI to have the discussion -- Axolo automatically opens (and archives) a channel dedicated to the MR discussion.
