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.
Issue view
Whenever you open a Jira issue you'll see a new section on the left called Related issues. It's organized in tabs and you can click on them to unfold the list of matching issues. Configuration of the tabs is described in the next section.
SCREENSHOT
Please keep in mind that at most 100 issues will be displayed per each tab. If there is an error in the query the tab won't be displayed.
