Summary

At the moment, JIRA Core board cards do not display priority icons.
According to this Atlassian blog post, the information that is displayed by default on the cards, are:

• Name of the task
• Assignee
• Due date

Suggestion

As a user, it would be great to have the ability to display priority icons on Board cards for JIRA Core boards.
It makes much easier to see important and critical issues. The ability to select/filter which priority levels actually display on the cards is also important to this functionality.
