You can display related issues in the issue view to give more context or highlight priority work to the users to make sure everyone is on the same page.
For example you can see what other issues were reported by the same user in Service desk projects. You can highlight project top priority blockers. It is all highly configurable with JQL queries and simple templating and you can fit the queries to your team needs.
