People often open a JIRA issue by URL, and then start working on it. They have to manually refresh (usually after seeing an email notification) to see any changes to the ticket like edits to the description or new comments, or any other change for that matter by other users (or even themselves in a different window).
Similar to other agile boards, is there any mechanism to periodically check if a ticket has changed since the page was loaded? Examples might be popup message or link to refresh the page.
